A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. We present a resonant CPSS consisting of closely spaced wire helices. Simulation results demonstrate that the design can operate over ±20° angle of incidence variation and has a bandwidth of about 10% at normal incidence. A suggested design case is presented, where the CPSS is implemented in a shared aperture circular polarization offset reflector antenna for satellite communication in the K u band uplink of Australia at 17.3 GHz < f < 18.1 GHz.
