Abstract
A system for duplex transmission and reception utilizing circular polarization wherein a pair of linear polarized orthogonal antennas is coupled to a transmitter through a hybrid coupler and a receiver is coupled to the antennas via the same hybrid coupler by using the port isolated from the transmitter. The hybrid may be a quadrature hybrid coupler or may comprise a 180 degree hybrid combined with a 90 degree phase shift network. Embodiments are shown for receiving a first reflection (opposite handed sense) circular polarized wave and alternatively, for receiving a second reflection (same handed sense) (multi-path) circular polarized wave.
