Toward Using Monostatic Antennas with Near-Field Cancellation Technique in IBFD Phased Arrays

Résumé

This paper presents an S-Band monostatic 2x2 patch array, with shared radiating elements among Tx and Rx, for In-Band Full-Duplex (IBFD) applications. In this array, self-interference cancellation (SIC) is achieved by locally implementing the near field cancellation (NFC) technique at each single patch by a multi-point differential feeding, which also ensures global SIC at the array level. Moreover, to identify the major coupling paths between array ports that contribute to cancellation, we provide some coupling matrices as a new way to represent the magnitude and phase combinations of interand intra-port coupling. In addition to that, we demonstrate the variation of cancellation level as the Tx and Rx beams are steered independently.
