Antenna Preprocessing and Element-Pattern Shaping for Multi-Band mmWave Arrays M

Abstract

The ability to pre-process incident RF signals on a single-antenna aperture in a multi-port antenna/receiver archi- tecture with reconfigurable element patterns can allow unique functionalities, that are distinct from traditional transceivers with single-port antennas. The multiple ports allow reconfig- urable passive spatial signal processing before the transceiver through element-pattern synthesis including element maxima and notch control. In this article, we show that when combined in an MIMO
