Sistemet Radio të fiksuar; Karakteristikat dhe kërkesat për pajisjet dhe antenat pikë-pikë; Pjesa 4-1: Kërkesat e sistemit të varur për antenat

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

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 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 [i.1].
