Abstract :
This paper shows the comparison of some of the most important satellite antenna feeders for fixed applications. The design procedure of the feeders is carried out in order to contrast their main electrical features with their manufacturing tolerance. The considered characteristics are: antenna gain, beamwidth, cross-polarization discrimination, side and back lobes relation. A mechanical tolerance of +/- 10 μm can represent cross-polarization selectivity variations wider than 10 dB.
