This part of IEC 61114 applies to individual and collective receiving antennas for satellite broadcast transmissions in the 11/12 GHz band. This standard mainly applies to paraboloidal reflector antennas, which include offset paraboloidal reflector antennas, Cassegrain reflector antennas and other equivalent types. It also applies to planar array antennas. However, the supporting mast and the radome are not included in this standard. This standard applies to the following six types of antennas. a) Antenna of a single antenna system to receive signals from a single satellite 1) linearly polarized single-beam antenna; 2) circularly polarized single-beam antenna. b) Antenna of a single antenna system to receive signals from two or more than two satellites 1) linearly polarized multiple beam antenna; 2) circularly polarized multiple beam antenna. c) Antenna of a multiple antenna system to receive signals from two or more than two satellites 1) linearly polarized system of single-beam antenna; 2) circularly polarized system of single-beam antenna. Typical configurations of these six types are illustrated in figure 1. The object of this part of IEC 61114 is to define the conditions and methods of measurement to be applied. This standard does not specify performance requirements. It is assumed that for some measurements the SHF converter will be removed from the antenna, leaving access to an r.f. port.
