Abstract
A simultaneous transmit and receive (STAR) system comprises a plurality of radiating elements and a plurality of antenna transmit/receive (T/R) elements. The plurality of antenna T/R elements are each in operable communication with a respective radiating element. Each T/R element comprises a transmit channel, a receive channel, a switch, and a directional coupler. The directional coupler comprises an RF input in operable communication with an antenna array receiving signals, an RF output coupling the received signals to an input of the receive channel, and a coupled input operably coupled to the switch. If the switch is set to a predetermined state, the respective transmit channel couples an active cancellation signal to the coupled input of the directional coupler to cancel at least some coupling effects arising on an input to the receive channel, arising from operation of at least some of the T/R elements in the array.
