Abstract : A microstrip antenna system that is capable of simultaneously transmitting an outgoing circularly polarized wave while receiving an incoming circularly polarized wave using a microstrip patch antenna element and a signal processing network is disclosed. The signal processing system connects the antenna element to a transmitter and receiver and produces a phase-shifted transmitted signal in order to isolate the receiver from the transmitted signal by nulling it.
