Fixed Radio Systems - Multipoint Equipment and Antennas - Part 3: Multipoint Antennas

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 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

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

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
NOTE: See Recommendation ITU-R F.1399 [i.3].

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

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

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

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).

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.

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.

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

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

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
