Polarization Discrimination for Satellite Communications

摘要

It appears feasible for satellite relay systems to provide polarization discrimination of 20 to 30 dB (or more with adaptive antennas) in the antenna main beam. Thus, if the systems are designed to operate with smaller wanted to unwanted signal ratios than those provided by polarization discrimination, it should be possible to double the effective spectrum available by using it independently on two orthogonal polarizations.
