Fixed Radio Systems - Characteristics and requirements for point-to-point equipment and antennas - Part 4-1: System-dependent requirements for antennas

TThe 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 86 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 Definitions, symbols and abbreviations 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. 3.3 Abbreviations 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 86 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 66 GHz; Range 7: 71 GHz to 86 GHz. 5 Classification of antennas Antenna classification presented in the present document is based on RPE and XPD parameters. 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 to figures 1 to 3 and table 1. 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 falls 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 1: Figures 1 to 3 report 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. NOTE 2: In frequency range 7 (71 GHz to 86 GHz) no classes are defined. In EN 302 217-4-2 [4], the maximum RPE is defined only in terms of gain relative to the maximum gain in the main beam axis. -25-20-15-10-50510150102030405060708090100110120130140150160170180Azimuth DegreesMaximum Gain (dBi)Class 2Class 3Class 4 Figure 1: Co-polar limits for actual RPE masks of antenna classes
