Simultaneous Transmit and Receive with Shared-Aperture Arrays

摘要

An approach based on shared aperture antennaarray is researched for simultaneous transmit and receive (STAR)applications. The proposed configuration is a 10×10 antenna arrayof circularly-polarized (CP) elements with 50 elements, somewhatsparsely distributed, dedicated for Tx while the remainingelements dedicated for Rx. The high isolation is achieved betweenTx and Rx elements at the expense of higher sidelobe levels, whichis an inherent property of sparse antenna arrays. To demonstratethe performance of the proposed STAR configuration, numericalmodelling is conducted using multilevel fast multipole method(MLFMM) solver in Altair FEKO.
