An antenna system capable of achieving simultaneous transmit and receive (STAR) operation over a wide bandwidth includes a ring array of TEM horn elements and a centrally located monocone or bicone antenna. The TEM horn elements each include a capacitive feed. The elements of the ring array are excited using a phasing scheme that results in signal cancellation at the location of the central element. The ring array may serve as either the transmit antenna or the receive antenna.
