Radiation Control Using a Non-Uniform Array Antenna for WPT

Abstract

  Microwave method is proposed as the WPT’s system used in SSPS and power transfer to an EV. Formerly, we used amplifiers with variable gain and attenuator to get the desirable radiation pattern. In this research, we propose a method to realize the same radiation patterns controlling the amplitude by means of keeping uniform amplitude and controlling the element spacing. We show the design method and validity by simulation.
