Foreword
This European Telecommunication Standard (ETS) has been produced by the Transmission and
Multiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).
Transposition dates
Date of adoption of this ETS: 4 June 1999
Date of latest announcement of this ETS (doa): 30 September 1999
Date of latest publication of new National Standard

Introduction
The purpose of this ETS is to define only those antenna parameters necessary to ensure optimum
frequency co-ordination between communication services in the frequency range 3 GHz to 60 GHz.
Additional parameters appropriate to system implementation may be subject to agreement between the
equipment purchaser and supplier. Further guidance is provided in annex A.

1 Scope
This European Telecommunication Standard (ETS) addresses the minimum requirements for
single main beam, linear polarization, directional antennas to be adopted in conjunction with
Point-to-Point (P-P) systems operating in the frequency range 3 GHz to 60 GHz.
Single polarization antennas, dual polarization antennas, dual band/single polarized antennas and
dual band/dual polarization antennas are considered.
A regulatory authority may impose tighter requirements than the minimum values given in this ETS,
in order to maximize the use of the scarce spectrum resources.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
antenna inter-port isolation: it is the ratio in dB of the power level applied to one port of a multi-port
antenna to the power level received in any other port of the same antenna as function of frequency
antennas: that part of the transmitting or receiving system that is designed to radiate and/or receive
electromagnetic waves
co-polar pattern: diagram representing the radiation pattern of the antenna under test when the
reference antenna is similarly polarized, scaled in dBi or dB relative to the measured antenna gain
cross-polar discrimination: difference in dB between the co-polarized main beam gain and the cross-
polarized signal measured within a defined region

cross-polar pattern: diagram representing the radiation pattern of the antenna under test when the
reference antenna is orthogonally polarized, scaled in dBi or dB relative to the measured antenna gain
frequency band: frequency band of an antenna is the band of frequencies over which the performance
characteristics of the antenna are within specified limits
gain: ratio of the radiation intensity, in the main beam axis to the radiation intensity that would be obtained
if the power accepted by the antenna were radiated isotropically. Value measured in dBi
half power beamwidth: angle, relative to the main beam axis, between the two directions at which the
measured co-polar pattern is 3 dB below the value on the main beam axis
input port(s): flange(s) or connector(s) through which access to the antenna system is provided. This is

3.3 Abbreviations
For the purposes of this ETS, the following abbreviations apply:

4 Frequency ranges
This ETS applies to sub-bands within 3 GHz to 60 GHz frequency band. Fixed link frequency allocations
are in accordance with the WARC 1992 Final Acts [1] as given in ITU-R Recommendation F.746-2 [2] and
other frequency plans.
For the purposes of this ETS, the overall frequency range 3 GHz to 60 GHz is divided into six frequency
ranges as follows:
Range 1: 3 GHz to 14 GHz;
Range 2: 14 GHz to 20 GHz;
Range 3: 20 GHz to 24 GHz;
Range 4: 24 GHz to 30 GHz;
Range 5: 30 GHz to 47 GHz;
Range 6: 47 GHz to 60 GHz.
5 Classification of antennas
With respect to antenna gain, two gain categories are applicable:
Gain category 1: those antennas which require low gain for co-ordination purposes;
Gain category 2: those antennas which require high gain for co-ordination purposes.
With respect to Radiation Pattern Envelope (RPE), four classes have been identified:
Class 1: those antennas required for use in networks where there is a low interference
potential;
Class 2: those antennas required for use in networks where there is a high interference
potential;
Class 3: those antennas required for use in networks where there is a very high
interference potential;
Class 4: those antennas required for use in networks where there is an extremely high
interference potential.
With respect to cross-Polar Discrimination (XPD), two XPD performance categories have been identified
(refer to subclause 6.2, table 1):
XPD category 1: those antennas required to have standard cross-polar discrimination;
XPD category 2: those antennas required to have high cross-polar discrimination.
6 Electrical characteristics
The antenna manufacturer shall state, for each antenna type, the frequency band of operation and
antenna gain at least at the frequency band edges and at mid-band. An antenna which employs a radome
shall meet the requirements of this ETS with the radome in place.

The antenna system shall radiate a linear (single or dual) polarized wave.
The method of measurement shall be in accordance to IEC 60835-2-2 [3].
6.1 Radiation Pattern Envelope (RPE)
RPE(s) for each class are included, in order to present the maximum flexibility to administrations for
optimized co-ordination.
The co-polar and cross-polar radiation pattern measured in the azimuth plane for both polarizations, shall
not exceed the RPE(s) defined in the following list:
Range 1:
Class 1: figure 2a);
Class 2: figure 2b);
Class 3: figure 2c);
Class 4: figure 2d).
Range 2:
