Abstract: The inherent multiharmonic characteristics of time-modulated antenna arrays (TMAs) offer significant potential for generating multiple beams under a single radio frequency (RF) chain.

Abstract: This paper introduces a new method, called multi-port load modulation, allowing one to improve the delta RCS of any passive transponder. By switching simultaneously the loads connected to a ...
