US Patent 7526249 Satellite ground station to receive signals with different polarization modes

A satellite ground station to receive signals with different polarization modes is described. In one example, the system includes a method of receiving a signal from a satellite at a feed, producing a first signal having a first polarization and a second signal having a second orthogonal polarization from the feed signal, and synthesizing a third signal having a third polarization different from the first and second signal and a fourth signal having fourth polarization orthogonal to the third polarization.
