Abstract
A transceiver element for controlling the phase of a microwave signal passing therethrough. The transceiver element includes a plurality of switching means arranged to steer a microwave frequency signal provided by a radar system through a nonreciprocal phase shifter to a phased array antenna during a transmit mode, and to steer a microwave frequency signal received by the phased array antenna through the nonreciprocal phase shifter to the radar system during a receive mode. The microwave frequency signal passes through the phase shifter in the same direction during both the transmit and receive modes. A set of control signals is fed to such switching means and the phase shifter of the transceiver element to provide collimated and directed beams of microwave energy during the transmit mode and the receive mode.
