These systems use various multiple access schemes. Electronically steerable antennas and circularly polarized antennas are not considered in the present document.

Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission
and Multiplexing (TM).
The purpose of the present document is to define the antenna performance standards necessary to ensure optimum
frequency co-ordination between the systems and/or different services by the Regulatory Authorities in the 3 GHz to
11 GHz band. These nominal frequency limits have been chosen to reflect the WRC 2000 Final Acts [6] and the
frequency plans as given in CEPT Recommendation T/R 13-02 [1] and ITU-R Recommendation F.748 [5].
Point-to-multipoint antennas, whether integrated within station equipment or not, may need to meet environmental,
mechanical and electrical characteristics not covered by the present document, in order that the systems will operate as
intended. Additional parameters and characteristics may be subject to agreement between the equipment purchaser and
the supplier; these are considered and guidance is provided in annex A.

1 Scope
The present document specifies the essential electrical requirements for linear polarization, fixed beam antennas to be

operating in frequency bands from 3 GHz to 11 GHz. These systems use various multiple access schemes.
Electronically steerable antennas and circularly polarized antennas are not considered in the present document.
Only in exceptional circumstances, and after a consultation period with operators and manufacturers, the Regulatory
Authority may impose the use of tighter requirements than the minimum values given in the present document, in order
to maximize the use of scarce spectrum resources.
For some high gain, point-to-multipoint requirements, antennas may be used having performance as per the appropriate
point-to-point antenna standard. For these antennas, minimum requirements are given in EN 300 833 [8].

5 Types and classification of antennas
5.1 Antenna types
The present document addresses fixed beam antennas used in the Central (CS) and Terminal (TS) stations including
Repeaters (RS).
The antennas are used in a system which can generally be described as in figure 1.
TS


 TS
Exchange
CS
RS

CS: Central Station, which is linked to all remote stations (repeater or terminal stations) by microwave
transmission paths.
TS: Terminal Station (outstation with subscriber interfaces).
RS: Repeater Station (radio repeater outstation with or without subscriber interfaces). A RS may serve one or
more TSs.

Figure 1: General point-to-multipoint system architecture
These antennas shall be grouped into the following types:
Central and repeater stations:
• Omni-directional;
• Sectored:
- Single-beam;
- Multi-beam;
• Directional, conforming to the requirements for TS antennas.
Terminal stations: Directional.
Repeater antennas can be of either Central (CS) or Terminal (TS) station types.
5.2 Antenna classifications
5.2.1 CS classes
With respect to the azimuthal Radiation Pattern Envelope (RPE), three classes may be identified in different frequency
sub-ranges for Central Station (CS) sectored antennas (CS1,CS2,CS3) and two classes may be identified for
multi-beam antennas (CSMB1,CSMB2):
• class CS 1;

• class CS 2;
• class CS 3;
• class CSMB1;
• class CSMB2.
These classes allow flexibility for a variety of different systems, and may be generally appropriate for low, medium and
higher density deployments respectively.
With respect to the azimuthal RPE for omni-directional CS antennas, no requirement for separate classes has been
identified.
5.2.2 TS classes
With respect to the radiation pattern envelope (RPE), a number of classes have been identified for Terminal Station
(TS) directional antennas:
• class TS 1;
• class TS 2;
• class TS 3;
• etc.
These classes allow flexibility for a variety of different systems and deployment conditions.
6 Electrical characteristics
For the purpose of the present document, an antenna is specific to Type, Class, Range, the frequency band of operation
and the mid-band gain. An antenna which employs a radome shall meet the requirements of the present document with
the radome in place.
A 0° reference direction shall be defined for each antenna. The radiation characteristics in the present document are all
referred to this 0° reference direction.
6.1 Terminal Station (TS) antennas
The RPEs and gain parameters apply for both horizontal and vertical linearly polarized antennas.
6.1.1 TS Radiation Pattern Envelope (RPE)
The co-polar and cross-polar radiation patterns for both azimuth and elevation (see figure 2) shall not exceed the RPEs
defined in the following list:
- range 1 (3,0 GHz to 5,9 GHz):
- class TS 1: table 1;
- class TS 2: table 2;
- class TS 3: table 3;
- class TS 4: table 4;

6.1.2 TS minimum boresight gain
The TS RPEs specified in tables 1 to 12 inclusive are for maximum allowed co- and cross-polar gains, relative to
boresight actual gain.
The TS antenna shall meet the minimum boresight gain described by the following expression:
- Minimum boresight gain = ROUND (0,85 f + 5) dBi;
0
where f is the nominal centre frequency in GHz and ROUND ( ) means rounded to the nearest integer value.
0
Antenna boresight (and associated gain) does not necessarily correspond to the 0° reference direction (and its associated
gain).
6.2 Central Station (CS) sectored single beam antennas
6.2.1 CS azimuth Radiation Pattern Envelope (RPE), sectored
The Central Station azimuth RPEs for sectored (i.e. not for multi-beam and not for omni-directional) antennas are
defined in the following list for sector beamwidths in the range 15° to 180°:
• class CS 1: table 13;
• class CS 2: table 14;
• cl
