Abstract: A system may include a double differential-fed dual-polarized 2.4 GHz, microstrip patch antenna with extremely high interport isolation for shared antenna architecture based in-band full duplex (IBFD) transceivers. The presented antenna configuration is based on four ports linearly polarized single radiating element with differential feeding for both transmit (Tx) and receive (Rx) operation. The double differential feeding using two identical 3 dB/180° ring hybrid couplers with nice amplitude/phase balance effectively suppresses the interport RF leakage to achieve very high isolation. Strong amplitude and phase balance of 3 dB/180° ring hybrid coupler can provide a better SIC performance as compared to DFN based on Wilkinson power divider with un-equal length microstrip lines, thus supplying an elite level of suppression in means of self-interference at Tx.
