Introduction
The purpose of the present document is to define antenna parameters, which are relevant to Fixed Radio Systems (FRS),
including those considered essential for conformity to the R&TTE Directive [1]. Limits are set out in
EN 302 217-4-2 [4].
Additional parameters appropriate to system implementation may be subject to agreement between the equipment
purchaser and supplier. Further guidance is provided in annex B.

1 Scope
The present document summarizes all requirements for single main beam, linear polarization, directional antennas to be
adopted in conjunction with Point-to-Point (PP) systems operating in the frequency range 1 GHz to 60 GHz.
Single polarization antennas, dual polarization antennas, dual band/single polarized antennas and dual band/dual
polarization antennas are considered.
Description and limits for parameters relevant to essential requirements under article 3.2 of the R&TTE Directive [1]
are given in EN 302 217-4-2 [4].
For other parameters and general information that does not affect the R&TTE Directive [1] "essential requirements"
mentioned above, description and limits are set out in the present document.
There are a number of different antenna types for various applications, the principles by which they are classified are
given in clause 5.
The present document does not cover aspects related to test procedures and test conditions, which are covered by the
scope of EN 301 126-3-1 [2].
Guidance on the definition of radio parameters relevant to the essential requirements under article 3.2 of the
R&TTE Directive [1] for DFRS may be found in TR 101 506 (see bibliography).

3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 302 217-1 [3] apply.
3.2 Symbols
For the purposes of the present document, the symbols given in EN 302 217-1 [3] apply.

For the purposes of the present document, the abbreviations given in EN 302 217-1 [3] apply.
4 Frequency bands
The present document defines the characteristics and requirements of antennas in the frequency range from 1 GHz to
60 GHz.
For technical commonalities that range is here divided into sub-ranges as follows:
Range 0: 1 GHz to 3 GHz;
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
Antenna classification presented in the present document is based on RPE and XPD parameters.
NOTE: It should be noted that in previous EN 301 751, based on EN 300 631 and EN 300 833 (see references for
these ENs in the bibliography), there was an additional classification regarding "low gain" and "high
gain", considered no longer appropriate since R&TTE Directive [1] came into force.
5.1 Radiation Pattern Envelope (RPE) classes
The RPE directional characteristic (co-polar and cross-polar) impacts the interference situation in the network planning
and a trade-off between a highly demanding RPE and the cost/size/weight of the antennas, compatible with the
constraints given by present and future networks is then advisable.
With respect to the Radiation Pattern Envelope (RPE), four classes (RPE classes 1 to 4) have been identified according
maximum co-polar limits for any actual RPE mask in significant range of off-axis azimuth angles. The subdivision in
those classes is also depending on given frequency ranges of operation according figures 1 to 3 and table 1.
ETSI
7 ETSI EN 302 217-4-1 V1.1.3 (2004-12)
Figures 1 to 3 are intended only for defining subdivision of antennas in directivity classes; actual limits options
for declaration of conformance to essential requirements under article 3.2 of the R&TTE Directive [1] are
defined only in EN 302 217-2-2 (see bibliography).
When more than one actual standardized RPE fall within the same class, a sub-class indicative (A, B, C, etc.) will be
used according their more demanding RPE limit in angles closer to the intended direction.
NOTE: Figures 1 to 3 reports limits for any actual RPE mask of classes 2, 3 and 4 antennas; class 1 antennas are
defined as those which actual RPE mask exceeds class 2 limits. It should also be noted that, while the
above subdivision is objectively based on actual antenna characteristics, in previous EN 300 631 and
EN 300 833 (see both references in the bibliography) the definition of classes 1 to 4 was based on
different subjective concepts of "low, high, very high, extremely high interference potential on the
network"; those definitions are no longer appropriate since R&TTE Directive [1] came into force,
because of the possible connection to the regulatory frame. Nevertheless only in few cases the RPEs,
transferred in the present document or in EN 302 217-4-2 [4], have actually changed class number from
those previous ENs.
