Abstract
Feed networks and methods of using the same to achieve high levels of self-interference cancellation (SIC) in Simultaneous Transmit and Receive (STAR) systems are provided. SIC at the antenna feed network alone can be as high as 100 dB. This can be done by employing entirely low-cost, low-profile passive circuits. The feed network creates a perfect anti-phase path that cancels the high power self-interference signal at the receive port.
