A Compact Beam Steering Dielectric Resonator Antenna for Wireless Power Transfer

Abstract

Design and simulation of a low profile and compact beam steering dielectric resonator antenna are discussed. A central feed primary monopole antenna is used to excite a DR, and another secondary monopole is used to achieve a unidirectional antenna. In order to have the desired direction, a fixed phase shift is added to all monopole antennas due to the physical distance. By switching between five monopole secondary antennas, a 60-degree 3-dB bandwidth pattern with the coverage of a half space is achieved.
