  Abstract

In this paper, we propose a system in which an electronically steerable parasitic array radiator (ESPAR) antenna is applied to a microwave power transfer (MPT) system, which is a wireless power transmission system using a radio frequency (RF) signal. In addition, we also present the 3x3 ESPAR antenna design method and characteristics evaluation results for use in this system. When an ESPAR antenna is used for a transmitter of an MPT system, power consumption and complexity can be effectively reduced. Through simulation, it has been confirmed that the designed 3x3 ESPAR antenna can form a beam pattern for 3D beamforming, and it has been confirmed that it effectively supports the 2.45 ㎓ band even when various reactance sets are applied.
