A reflect antenna element having a receive antenna section and a transmit antenna section. Each section has a cavity, a conductive element in registration with the cavity, and a ground plane conductor having a slot. A strip conductor has portions thereof disposed over the slots and the ground planes conductor. The strip conductor and underlying ground plane conductor form a microstrip transmission line for coupling energy received by the receive antenna section to the transmit antenna section. The transmit antenna section and receive antenna section are configured to operate with orthogonal polarizations. An amplifier is disposed in circuit with the transmission line.
