A Study of Improve Efficiency of Broad-Angle Rectenna Using Hybrid Coupler

Abstract

In a system that feeds relatively small electric power using microwaves, it is a problem to improve received power in various arrival directions in a power receiving device that is generally small. In this paper, we propose a rectenna that converts power in a wide range of incoming direction to DC with an array antenna that performs power synthesis by a hybrid circuit and report the results of verification by simulation and actual measurement.
