Self-Interference Leakage Estimation ‘N’ Cancellation Element: Design of an Active Self-Interference Cancellation Coupler

Monostatic radar systems as well as radars with separated but nearby-placed transmit and receive antennas are beneficial in terms of cost-efficiency and miniaturization, which is necessary for their integration into compact radar systems or mobile devices [1], [2] as well as for radar networks that demand reciprocal transmission channels between the nodes [3]. However, this lack of separation between the transmit (Tx) and receive (Rx) paths due to miniaturization implies only week isolation between Tx and Rx.
