Introduction

For the general background, rationale and structure of the present document see also the clause "Introduction" in ETSI

EN 302 326-2 [i.4].

1 Scope
1.1 General

The present document is applicable to antennas (stand-alone, dedicated or integral antennas according to the definitions

of terms in clause 3.1) used in MultiPoint (MP) Digital Fixed Radio Systems (DFRS) (see note 1) intended for use in

the frequency bands identified in ETSI EN 302 326-2 [i.4].

NOTE 1: Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless

Access (NWA), according to the NWA definition in Recommendation ITU-R F.1399 [i.3], are also

considered in the scope of the present document.

For Multipoint Fixed Radio Systems, antenna characteristics are not considered relevant to essential requirements under

article 3.2 of Directive 2014/53/EU [i.1] (see note 2). Antenna characteristics in the present document are considered

applicable whenever they are considered appropriate for the associated multipoint radio system.

NOTE 2: Rationale can be found in ETSI TR 101 506 [i.2].
1.2 Antenna types and operating frequency

The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and

circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually

perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular

polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.

The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or

circular polarized antennas) impact on the interference has to be considered in network planning. A number of antenna

options are defined in the present document.

Table 1 outlines the multipoint antenna types and their operating frequencies described in the present document.

NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Table 1: Antenna Types
Frequency Range Types Polarization Notes
(see note)

1 GHz to 3 GHz Directional Linear The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.

3 GHz to 5,9 GHz, Directional Linear The sectored single and omnidirectional antennas

5,9 GHz to 8,5 GHz Sectored single beam may have a symmetric or asymmetric radiation

and Sectored multi-beam pattern in the elevation plane. The sectored multi-

8,5 GHz to 11 GHz (up to 5,9 GHz only) beam antennas have a symmetric radiation pattern

Omnidirectional only.

1 GHz to 11 GHz Directional Circular The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam

30 GHz to 40,5 GHz Directional Linear The omnidirectional antennas may have a symmetric

and Sectored single beam or asymmetric radiation pattern in the elevation plane.

40,5 GHZ to 43,5 GHz Omnidirectional

NOTE: Attention is drawn to the fact that the specific operating bands are subject of CEPT or national licensing

rules. Currently applicable Fixed Service bands and channel plans are described in ETSI EN 302 326-2 [i.4],

although the applicability of these Fixed Service bands is at the discretion of the national administrations.

Therefore, the present document applies only to those bands which are allocated to the Fixed Service and/or

assigned by national regulations to MP applications on the date on which the EN was published.

1.3 Profiles

The present document and associated ETSI EN 302 326-2 [i.4] for equipment and systems allows many distinct types of

equipment, several different antenna types and several ways in which they might be interconnected to form a network.

However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called

"profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.

Annex A discusses Equipment, Antennas and System Profiles for multipoint systems in the scope of this multi-part

deliverable.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms (see note) apply:

NOTE: For the correct understanding and application of the requirements in the present document, the definitions

below are identified, when relevant, with the use of italic characters (e.g. azimuth plane).

antenna: part of the transmitting or receiving system designed to transmit or receive electromagnetic radiation

azimuth plane: reference plane (see note) from which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally horizontal (see also tilt). The azimuth plane is generally mechanically identified

by reference to the technical description for actual antennas for testing and deployment purposes.

Sectorial and omnidirectional antennas might have intrinsic down-tilt of few degrees. In such cases, it

would be more theoretically appropriate reference to a "conical" surface rather than a plane. However, tilt

is generally compensated for by the test set antenna mounting (i.e. by tilting up the antenna test set

mounting by an equivalent quantity) and the assessment is done by rotating the antenna rather than the

receiving instrument. The test is thus performed in such a way that the measurements may be considered

equivalent to those made in a true azimuth plane.

Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations

co-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the wanted plane

of polarization (for linear polarization) or wanted direction of rotation (for circular polarization)

NOTE: The wanted plane or direction of rotation may be defined when the parameter is being measured by the

plane or direction of rotation of the reference antenna.

co-polar pattern: diagram representing the co-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured antenna gain.

cross-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the unwanted

plane of polarization (for linear polarization) or unwanted direction of rotation (for circular polarization)

NOTE: The unwanted plane of polarization of a linear polarized antenna is defined as the plane which lies at right

angles to the wanted plane. The unwanted direction of rotation of a circular polarized antenna is defined

as that which is opposite to the wanted direction.

cross-polar pattern: diagram representing the cross-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured co-polar antenna

gain.

dedicated antenna: antenna specifically designed for being attached to the radio equipment (i.e. with special

mechanical fixing to the antenna port of the specific radio supplied), but can be separated from the equipment (typically

for transport purpose) by using normal tools

electrical tilt: angular shift in elevation of the direction of maximum gain of the antenna by a specific electrical design

of the antenna

10 ETSI EN 302 326-3 V2.1.1 (2021-09)

elevation plane: reference plane, orthogonal to the azimuth plane, to which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally vertical. For directional, single beam sectored and multi-beam sectored antennas,

the elevation plane is centred to the azimuth zero degree (0°) reference direction (within each beam in

multi-beam). For omnidirectional antennas, the elevation plane is not limited in the azimuth plane

direction and is specific only to a given measurement.

gain: ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power

accepted by the antenna was radiated isotropically

gain ripple: (for omnidirectional antennas) maximum variance of the gain in the azimuth plane around the actual gain

of the antenna under test

NOTE: Figure 1 shows the relationship between the X dB gain ripple, measured minimum and maximum gains in

the azimuth plane, and the declared nominal gain and gain tolerance of an omnidirectional antenna.

Figure 1: Gain ripple for an omnidirectional antenna

gain tolerance: tolerance of the nominal gain, as declared by the supplier according to the principles shown in

figures 1 and 2

integral (integrated) antenna: antenna which is declared as part of the radio equipment by the manufacturer; it is not

physically separable from the equipment

isotropic radiator: hypothetical, lossless antenna with homogenous radiation intensity in all directions

Introduction

For the general background, rationale and structure of the present document see also the clause "Introduction" in ETSI

EN 302 326-2 [i.4].
ETSI
---------------------- Page: 6 ----------------------

1 Scope
1.1 General

The present document is applicable to antennas (stand-alone, dedicated or integral antennas according to the definitions

of terms in clause 3.1) used in MultiPoint (MP) Digital Fixed Radio Systems (DFRS) (see note 1) intended for use in

the frequency bands identified in ETSI EN 302 326-2 [i.4].

NOTE 1: Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless

Access (NWA), according to the NWA definition in Recommendation ITU-R F.1399 [i.3], are also

considered in the scope of the present document.

For Multipoint Fixed Radio Systems, antenna characteristics are not considered relevant to essential requirements under

article 3.2 of Directive 2014/53/EU [i.1] (see note 2). Antenna characteristics in the present document are considered

applicable whenever they are considered appropriate for the associated multipoint radio system.

NOTE 2: Rationale can be found in ETSI TR 101 506 [i.2].
1.2 Antenna types and operating frequency

The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and

circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually

perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular

polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.

The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or

circular polarized antennas) impact on the interference has to be considered in network planning. A number of antenna

options are defined in the present document.

Table 1 outlines the multipoint antenna types and their operating frequencies described in the present document.

NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Table 1: Antenna Types
Frequency Range Types Polarization Notes
(see note)

1 GHz to 3 GHz Directional Linear The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.

3 GHz to 5,9 GHz, Directional Linear The sectored single and omnidirectional antennas

5,9 GHz to 8,5 GHz Sectored single beam may have a symmetric or asymmetric radiation

and Sectored multi-beam pattern in the elevation plane. The sectored multi-

8,5 GHz to 11 GHz (up to 5,9 GHz only) beam antennas have a symmetric radiation pattern

Omnidirectional only.

1 GHz to 11 GHz Directional Circular The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam

30 GHz to 40,5 GHz Directional Linear The omnidirectional antennas may have a symmetric

and Sectored single beam or asymmetric radiation pattern in the elevation plane.

40,5 GHZ to 43,5 GHz Omnidirectional

NOTE: Attention is drawn to the fact that the specific operating bands are subject of CEPT or national licensing

rules. Currently applicable Fixed Service bands and channel plans are described in ETSI EN 302 326-2 [i.4],

although the applicability of these Fixed Service bands is at the discretion of the national administrations.

Therefore, the present document applies only to those bands which are allocated to the Fixed Service and/or

assigned by national regulations to MP applications on the date on which the EN was published.

1.3 Profiles

The present document and associated ETSI EN 302 326-2 [i.4] for equipment and systems allows many distinct types of

equipment, several different antenna types and several ways in which they might be interconnected to form a network.

However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called

"profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.

Annex A discusses Equipment, Antennas and System Profiles for multipoint systems in the scope of this multi-part

deliverable.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms (see note) apply:

NOTE: For the correct understanding and application of the requirements in the present document, the definitions

below are identified, when relevant, with the use of italic characters (e.g. azimuth plane).

antenna: part of the transmitting or receiving system designed to transmit or receive electromagnetic radiation

azimuth plane: reference plane (see note) from which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally horizontal (see also tilt). The azimuth plane is generally mechanically identified

by reference to the technical description for actual antennas for testing and deployment purposes.

Sectorial and omnidirectional antennas might have intrinsic down-tilt of few degrees. In such cases, it

would be more theoretically appropriate reference to a "conical" surface rather than a plane. However, tilt

is generally compensated for by the test set antenna mounting (i.e. by tilting up the antenna test set

mounting by an equivalent quantity) and the assessment is done by rotating the antenna rather than the

receiving instrument. The test is thus performed in such a way that the measurements may be considered

equivalent to those made in a true azimuth plane.

Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations

co-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the wanted plane

of polarization (for linear polarization) or wanted direction of rotation (for circular polarization)

NOTE: The wanted plane or direction of rotation may be defined when the parameter is being measured by the

plane or direction of rotation of the reference antenna.

co-polar pattern: diagram representing the co-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured antenna gain.

cross-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the unwanted

plane of polarization (for linear polarization) or unwanted direction of rotation (for circular polarization)

NOTE: The unwanted plane of polarization of a linear polarized antenna is defined as the plane which lies at right

angles to the wanted plane. The unwanted direction of rotation of a circular polarized antenna is defined

as that which is opposite to the wanted direction.

cross-polar pattern: diagram representing the cross-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured co-polar antenna

gain.

dedicated antenna: antenna specifically designed for being attached to the radio equipment (i.e. with special

mechanical fixing to the antenna port of the specific radio supplied), but can be separated from the equipment (typically

for transport purpose) by using normal tools

electrical tilt: angular shift in elevation of the direction of maximum gain of the antenna by a specific electrical design

of the antenna
ETSI
---------------------- Page: 9 ----------------------
10 ETSI EN 302 326-3 V2.1.1 (2021-09)

elevation plane: reference plane, orthogonal to the azimuth plane, to which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally vertical. For directional, single beam sectored and multi-beam sectored antennas,

the elevation plane is centred to the azimuth zero degree (0°) reference direction (within each beam in

multi-beam). For omnidirectional antennas, the elevation plane is not limited in the azimuth plane

direction and is specific only to a given measurement.

gain: ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power

accepted by the antenna was radiated isotropically

gain ripple: (for omnidirectional antennas) maximum variance of the gain in the azimuth plane around the actual gain

of the antenna under test

NOTE: Figure 1 shows the relationship between the X dB gain ripple, measured minimum and maximum gains in

the azimuth plane, and the declared nominal gain and gain tolerance of an omnidirectional antenna.

Figure 1: Gain ripple for an omnidirectional antenna

gain tolerance: tolerance of the nominal gain, as declared by the supplier according to the principles shown in

figures 1 and 2

integral (integrated) antenna: antenna which is declared as part of the radio equipment by the manufacturer; it is not

physically separable from the equipment

isotropic radiator: hypothetical, lossless antenna with homogenous radiation intensity in all directions

left hand (anticlockwise) polarized wave: elliptically - or circularly - polarized wave, in which the electric field

vector, observed in any fixed plane, normal to the direction of propagation, rotates in time in a left-hand or

anticlockwise direction
maximum gain: highest gain (in any direction) of the antenna under test

mechanical tilt: angular shift in the elevation plane in the direction of maximum gain of the antenna when modifying

the physical mounting of the antenna

Nomadic Wireless Access (NWA): "Wireless access" application in which the location of the "end-user termination"

may be in different places but is stationary while in use

Introduction

For the general background, rationale and structure of the present document see also the clause "Introduction" in ETSI

EN 302 326-2 [i.4].

7 Final draft ETSI EN 302 326-3 V2.1.1 (2021-06)
1 Scope
1.1 General

The present document is applicable to antennas (stand-alone, dedicated or integral antennas according to the definitions

of terms in clause 3.1) used in Multipoint (MP) Digital Fixed Radio Systems (DFRS) (see note 1) intended for use in

the frequency bands identified in ETSI EN 302 326-2 [i.4].

NOTE 1: Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless

Access (NWA), according to the NWA definition in Recommendation ITU-R F.1399 [i.3], are also

considered in the scope of the present document.

For Multipoint Fixed Radio Systems, antenna characteristics are not considered relevant to essential requirements under

article 3.2 of Directive 2014/53/EU [i.1] (see note 2). Antenna characteristics in the present document are considered

applicable whenever they are considered appropriate for the associated multipoint radio system.

NOTE 2: Rationale can be found in ETSI TR 101 506 [i.2].
1.2 Antenna types and operating frequency

The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and

circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually

perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular

polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.

The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or

circular polarized antennas) impact on the interference has to be considered in network planning. A number of antenna

options are defined in the present document.

Table 1 outlines the multipoint antenna types and their operating frequencies described in the present document.

NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Table 1: Antenna Types
Frequency Range Types Polarization Notes
(see note)

1 GHz to 3 GHz Directional Linear The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.

3 GHz to 5,9 GHz, Directional Linear The sectored single and omnidirectional antennas

5,9 GHz to 8,5 GHz Sectored single beam may have a symmetric or asymmetric radiation

and Sectored multi-beam pattern in the elevation plane. The sectored multi-

8,5 GHz to 11 GHz (up to 5,9 GHz only) beam antennas have a symmetric radiation pattern

Omnidirectional only.

1 GHz to 11 GHz Directional Circular The sectored and omnidirectional antennas may have

Sectored single beam a symmetric or asymmetric radiation pattern in the
Omnidirectional elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam

30 GHz to 40,5 GHz Directional Linear The omnidirectional antennas may have a symmetric

and Sectored single beam or asymmetric radiation pattern in the elevation plane.

40,5 GHZ to 43,5 GHz Omnidirectional

NOTE: Attention is drawn to the fact that the specific operating bands are subject of CEPT or national licensing

rules. Currently applicable Fixed Service bands and channel plans are described in ETSI EN 302 326-2 [i.4],

although the applicability of these Fixed Service bands is at the discretion of the national administrations.

Therefore, the present document applies only to those bands which are allocated to the Fixed Service and/or

assigned by national regulations to MP applications on the date on which the EN was published.

1.3 Profiles

The present document and associated ETSI EN 302 326-2 [i.4] for equipment and systems allows many distinct types of

equipment, several different antenna types and several ways in which they might be interconnected to form a network.

However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called

"profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.

Annex A discusses Equipment, Antennas and System Profiles for multipoint systems in the scope of this multi-part

deliverable.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms (see note) apply:

NOTE: For the correct understanding and application of the requirements in the present document, the definitions

below are identified, when relevant, with the use of italic characters (e.g. azimuth plane).

antenna: part of the transmitting or receiving system designed to transmit or receive electromagnetic radiation

azimuth plane: reference plane (see note) from which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally horizontal (see also tilt). The azimuth plane is generally mechanically identified

by reference to the technical description for actual antennas for testing and deployment purposes.

Sectorial and omnidirectional antennas might have intrinsic down-tilt of few degrees. In such cases, it

would be more theoretically appropriate reference to a "conical" surface rather than a plane. However, tilt

is generally compensated for by the test set antenna mounting (i.e. by tilting up the antenna test set

mounting by an equivalent quantity) and the assessment is done by rotating the antenna rather than the

receiving instrument. The test is thus performed in such a way that the measurements may be considered

equivalent to those made in a true azimuth plane.

Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations

co-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the wanted plane

of polarization (for linear polarization) or wanted direction of rotation (for circular polarization)

NOTE: The wanted plane or direction of rotation may be defined when the parameter is being measured by the

plane or direction of rotation of the reference antenna.

co-polar pattern: diagram representing the co-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured antenna gain.

cross-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the unwanted

plane of polarization (for linear polarization) or unwanted direction of rotation (for circular polarization)

NOTE: The unwanted plane of polarization of a linear polarized antenna is defined as the plane which lies at right

angles to the wanted plane. The unwanted direction of rotation of a circular polarized antenna is defined

as that which is opposite to the wanted direction.

cross-polar pattern: diagram representing the cross-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured co-polar antenna

gain.

dedicated antenna: antenna specifically designed for being attached to the radio equipment (i.e. with special

mechanical fixing to the antenna port of the specific radio supplied), but can be separated from the equipment (typically

for transport purpose) by using normal tools

electrical tilt: angular shift in elevation of the direction of maximum gain of the antenna by a specific electrical design

of the antenna
ETSI
---------------------- Page: 9 ----------------------
10 Final draft ETSI EN 302 326-3 V2.1.1 (2021-06)

elevation plane: reference plane, orthogonal to the azimuth plane, to which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally vertical. For directional, single beam sectored and multi-beam sectored antennas,

the elevation plane is centred to the azimuth zero degree (0°) reference direction (within each beam in

multi-beam). For omnidirectional antennas, the elevation plane is not limited in the azimuth plane

direction and is specific only to a given measurement.

gain: ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power

accepted by the antenna was radiated isotropically

gain ripple: (for omnidirectional antennas) maximum variance of the gain in the azimuth plane around the actual gain

of the antenna under test
0° RPE test Reference

Measured curve within declared
tolerance on nominal gain
−180°

NOTE: Figure 1 shows the relationship between the X dB gain ripple, measured minimum and maximum gains in

the azimuth plane, and the declared nominal gain and gain tolerance of an omnidirectional antenna.

Figure 1: Gain ripple for an omnidirectional antenna

gain tolerance: tolerance of the nominal gain, as declared by the supplier according to the principles shown in

figures 1 and 2

integral (integrated) antenna: antenna which is declared as part of the radio equipment by the manufacturer; it is not

physically separable from the equipment

isotropic radiator: hypothetical, lossless antenna with homogenous radiation intensity in all directions

left hand (anticlockwise) polarized wave: elliptically - or circularly - polarized wave, in which the electric field

vector, observed in any fixed plane, normal to the direction of propagation, rotates in time in a left-hand or

anticlockwise direction
maximum gain: highest gain (in any direction) of the antenna under test

mechanical tilt: angular shift in the elevation plane in the direction of maximum gain of the antenna when modifying

the physical mounting of the antenna

Nomadic Wireless Access (NWA): "Wireless access" application in which the location of the "end-user termination"

may be in different places but is stationary while in use

circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually

perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular

polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.

The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or

circular polarized antennas) impact on the interference to be considered in network planning. A number of antenna

options are defined in the present document.

Table 1 outlines the multipoint antenna types and their operating frequencies described in the present document.

NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Table 1: Antenna Types
Frequency Range Types Polarization Notes
(see note)
1 GHz to 3 GHz Directional Linear The sectored and omnidirectional antennas may
Sectored single beam have a symmetric or asymmetric radiation pattern in
Omnidirectional the elevation plane.

3 GHz to 5,9 GHz, Directional Linear The sectored single and omnidirectional antennas

5,9 GHz to 8,5 GHz Sectored single beam may have a symmetric or asymmetric radiation

and Sectored multi-beam pattern in the elevation plane. The sectored multi-

8,5 GHz to 11 GHz (up to 5,9 GHz only) beam antennas have a symmetric radiation pattern

Omnidirectional only.

1 GHz to 11 GHz Directional Circular The sectored and omnidirectional antennas may

Sectored single beam have a symmetric or asymmetric radiation pattern in
Omnidirectional the elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam
30 GHz to 40,5 GHz Directional Linear The omnidirectional antennas may have a
and Sectored single beam symmetric or asymmetric radiation pattern in the
40,5 GHZ to 43,5 GHz Omnidirectional elevation plane.

NOTE: Attention is drawn to the fact that the specific operating bands are subject of CEPT or national licensing

rules. Currently applicable Fixed Service bands and channel plans are described in ETSI

EN 302 326-2 [4], although the applicability of these Fixed Service bands is at the discretion of the national

administrations. Therefore, the present document applies only to those bands which are allocated to the

Fixed Service and/or assigned by national regulations to MP applications on the date on which the EN was

published.

1.3 Profiles

The present document and associated ETSI EN 302 326-2 [4] for equipment and systems allows many distinct types of

equipment, several different antenna types and several ways in which they might be interconnected to form a network.

However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called

"profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.

Annex A discusses Equipment, Antennas and Sytem Profiles for multipoint systems in the scope of this multi-part

deliverable.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms (see note) apply:

NOTE: For the correct understanding and application of the requirements in the present document, the definitions

below are identified, when relevant, with the use of italic characters (e.g. azimuth plane).

antenna: part of the transmitting or receiving system designed to transmit or receive electromagnetic radiation

azimuth plane: reference plane (see note) from which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally horizontal (see also tilt). The azimuth plane is generally mechanically identified

by reference to the technical description for actual antennas for testing and deployment purposes.

Sectorial and omnidirectional antennas might have intrinsic down-tilt of few degrees. In such cases, it

would be more theoretically appropriate reference to a "conical" surface rather than a plane. However, tilt

is generally compensated for by the test set antenna mounting (i.e. by tilting up the antenna test set

mounting by an equivalent quantity) and the assessment is done by rotating the antenna rather then the

receiving instrument. The test is thus performed in such a way that the measurements may be considered

equivalent to those made in a true azimuth plane.

Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations

co-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the wanted plane

of polarization (for linear polarization) or wanted direction of rotation (for circular polarization)

NOTE: The wanted plane or direction of rotation may be defined when the parameter is being measured by the

plane or direction of rotation of the reference antenna.

co-polar pattern: diagram representing the co-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured antenna gain.

cross-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the unwanted

plane of polarization (for linear polarization) or unwanted direction of rotation (for circular polarization)

NOTE: The unwanted plane of polarization of a linear polarized antenna is defined as the plane which lies at right

angles to the wanted plane. The unwanted direction of rotation of a circular polarized antenna is defined

as that which is opposite to the wanted direction.

cross-polar pattern: diagram representing the cross-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured co-polar antenna

gain.

dedicated antenna: antenna specifically designed for being attached to the radio equipment (i.e. with special

mechanical fixing to the antenna port of the specific radio supplied), but can be separated from the equipment (typically

for transport purpose) using normal tools

electrical tilt: angular shift in elevation of the direction of maximum gain of the antenna by a specific electrical design

of the antenna
ETSI

10 Draft ETSI EN 302 326-3 V2.1.0 (2020-08)

elevation plane: reference plane, orthogonal to the azimuth plane, from which Radiation Pattern Envelopes are

referenced

NOTE: This plane is nominally vertical. For directional, single beam sectored and multi-beam sectored antennas,

the elevation plane is that which contains the zero degree (0°) reference direction (within each beam in

multi-beam). For omnidirectional antennas, the elevation plane is not constrained in azimuth plane

direction and is specific only to a given measurement.

gain: ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power

accepted by the antenna was radiated isotropically

gain ripple: (for omnidirectional antennas) maximum variance of the gain in the azimuth plane around the actual gain

of the antenna under test

NOTE: Figure 1 shows the relationship between the X dB gain ripple, measured minimum and maximum gains in

the azimuth plane, and the declared nominal gain and gain tolerance of an omnidirectional antenna.

Figure 1: Gain ripple for an omnidirectional antenna

gain tolerance: tolerance on the nominal gain, as declared by the supplier according to the principles shown in

figures 1 and 2

integral (integrated) antenna: antenna which is declared as part of the radio equipment by the manufacturer; it is not

physically separable from the equipment, unless it is returned to the manufacturer premises

isotropic radiator: hypothetical, lossless antenna having equal radiation intensity in all directions

left hand (anticlockwise) polarized wave: elliptically - or circularly - polarized wave, in which the electric field

vector, observed in any fixed plane, normal to the direction of propagation, rotates in time in a left-hand or

anticlockwise direction
maximum gain: highest gain (in any direction) of the antenna under test

mechanical tilt: angular shift in elevation plane of the direction of maximum gain of the antenna by a change to the

physical mounting of the antenna

Nomadic Wireless Access (NWA): "Wireless access" application in which the location of the "end-user termination"

may be in different places but it is stationary while in use
NOTE: See Recommendation ITU-R F.1399 [i.3].

nominal gain: gain declared by the supplier to which gain assessment is to be referenced:

• For directional antennas: it is referenced to the maximum gain.

• For sectorial antennas: the supplier should make a declaration of the gain for the antenna, together with

maximum gain tolerance that should include the minimum gain within the declared sector. The gain of the

antenna, as measured, should not, therefore, exceed the declared gain at the declared upper gain tolerance

limit, nor should it be lower than the nominal gain at the declared lower gain tolerance limit (see figure 2).

• For omnidirectional antennas: it refers to the mean value of the gain ripple as shown in figure 1.

1 Scope
1.1 General

The present document is applicable to antennas (were it stand-alone, dedicated or integral antennas according the

definitions in clause 3.1) used in Multipoint (MP) Digital Fixed Radio Systems (DFRS) (see note 1) intended for use in

the frequency bands identified in ETSI EN 302 326-2 [4].

NOTE 1: Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless

Access (NWA), according to the NWA definition in Recommendation ITU-R F.1399 [i.3], are also

considered in the scope of the present document.

For Multipoint Fixed Radio Systems, antenna characteristics are not considered relevant to essential requirements under

article 3.2 of Directive 2014/53/EU [i.1] (see note 2). Antenna characteristics in the present document are considered

applicable whenever they are considered appropriate for the associated multipoint radio system.

NOTE 2: Rationale can be found in ETSI TR 101 506 [i.2].
1.2 Antenna types and operating frequency

The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and

circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually

perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular

polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.

The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or

circular polarized antennas) impact on the interference to be considered in network planning. A number of antenna

options are defined in the present document.

Table 1 outlines the multipoint antenna types and their operating frequencies described in the present document.

NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Table 1: Antenna Types
Frequency Range Types Polarization Notes
(see note)
1 GHz to 3 GHz Directional Linear The sectored and omnidirectional antennas may
Sectored single beam have a symmetric or asymmetric radiation pattern in
Omnidirectional the elevation plane.

3 GHz to 5,9 GHz, Directional Linear The sectored single and omnidirectional antennas

5,9 GHz to 8,5 GHz Sectored single beam may have a symmetric or asymmetric radiation

and Sectored multi-beam pattern in the elevation plane. The sectored multi-

8,5 GHz to 11 GHz (up to 5,9 GHz only) beam antennas have a symmetric radiation pattern

Omnidirectional only.

1 GHz to 11 GHz Directional Circular The sectored and omnidirectional antennas may

Sectored single beam have a symmetric or asymmetric radiation pattern in
Omnidirectional the elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam
30 GHz to 40,5 GHz Directional Linear The omnidirectional antennas may have a
and Sectored single beam symmetric or asymmetric radiation pattern in the
40,5 GHZ to 43,5 GHz Omnidirectional elevation plane.

NOTE: Attention is drawn to the fact that the specific operating bands are subject of CEPT or national licensing

rules. Currently applicable Fixed Service bands and channel plans are described in ETSI

EN 302 326-2 [4], although the applicability of these Fixed Service bands is at the discretion of the national

administrations. Therefore, the present document applies only to those bands which are allocated to the

Fixed Service and/or assigned by national regulations to MP applications on the date on which the EN was

published.

1.3 Profiles

The present document and associated ETSI EN 302 326-2 [4] for equipment and systems allows many distinct types of

equipment, several different antenna types and several ways in which they might be interconnected to form a network.

However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called

"profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms (see note) apply:

NOTE: For the correct understanding and application of the requirements in the present document, the definitions

below are identified, when relevant, with the use of italic characters (e.g. azimuth plane).

antenna: part of the transmitting or receiving system designed to transmit or receive electromagnetic radiation

azimuth plane: reference plane (see note) from which Radiation Pattern Envelopes are referenced

NOTE: This plane is nominally horizontal (see also tilt). The azimuth plane is generally mechanically identified

by reference to the technical description for actual antennas for testing and deployment purposes.

Sectorial and omnidirectional antennas might have intrinsic down-tilt of few degrees. In such cases, it

would be more theoretically appropriate reference to a "conical" surface rather than a plane. However, tilt

is generally compensated for by the test set antenna mounting (i.e. by tilting up the antenna test set

mounting by an equivalent quantity) and the assessment is done by rotating the antenna rather then the

receiving instrument. The test is thus performed in such a way that the measurements may be considered

equivalent to those made in a true azimuth plane.

Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations

co-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the wanted plane

of polarization (for linear polarization) or wanted direction of rotation (for circular polarization)

NOTE: The wanted plane or direction of rotation may be defined when the parameter is being measured by the

plane or direction of rotation of the reference antenna.

co-polar pattern: diagram representing the co-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured antenna gain.

cross-polar: used to define parameters (such as gain or radiation pattern) applicable to radiated signals in the unwanted

plane of polarization (for linear polarization) or unwanted direction of rotation (for circular polarization)

NOTE: The unwanted plane of polarization of a linear polarized antenna is defined as the plane which lies at right

angles to the wanted plane. The unwanted direction of rotation of a circular polarized antenna is defined

as that which is opposite to the wanted direction.

cross-polar pattern: diagram representing the cross-polar radiation pattern of an antenna under test

NOTE: It is scaled in dBi or, as used in the present document, in dB relative to the measured co-polar antenna

gain.

dedicated antenna: antenna specifically designed for being attached to the radio equipment (i.e. with special

mechanical fixing to the antenna port of the specific radio supplied), but can be separated from the equipment (typically

for transport purpose) using normal tools

electrical tilt: angular shift in elevation of the direction of maximum gain of the antenna by a specific electrical design

of the antenna

elevation plane: reference plane, orthogonal to the azimuth plane, from which Radiation Pattern Envelopes are

referenced

NOTE: This plane is nominally vertical. For directional, single beam sectored and multi-beam sectored antennas,

the elevation plane is that which contains the zero degree (0°) reference direction (within each beam in

multi-beam). For omnidirectional antennas, the elevation plane is not constrained in azimuth plane

direction and is specific only to a given measurement.

gain: ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power

accepted by the antenna was radiated isotropically

gain ripple: (for omnidirectional antennas) maximum variance of the gain in the azimuth plane around the actual gain

of the antenna under test

NOTE: Figure 1 shows the relationship between the X dB gain ripple, measured minimum and maximum gains in

the azimuth plane, and the declared nominal gain and gain tolerance of an omnidirectional antenna.

gain tolerance: tolerance on the nominal gain, as declared by the supplier according to the principles shown in

figures 1 and 2

integral (integrated) antenna: antenna which is declared as part of the radio equipment by the manufacturer; it is not

physically separable from the equipment, unless it is returned to the manufacturer premises

isotropic radiator: hypothetical, lossless antenna having equal radiation intensity in all directions

left hand (anticlockwise) polarized wave: elliptically - or circularly - polarized wave, in which the electric field

vector, observed in any fixed plane, normal to the direction of propagation, rotates in time in a left-hand or

anticlockwise direction
maximum gain: highest gain (in any direction) of the antenna under test

mechanical tilt: angular shift in elevation plane of the direction of maximum gain of the antenna by a change to the

physical mounting of the antenna

Nomadic Wireless Access (NWA): "Wireless access" application in which the location of the "end-user termination"

may be in different places but it is stationary while in use
NOTE: See Recommendation ITU-R F.1399 [i.3].
