Design, Simulation and Fabrication of Rectenna Circuit at S - Band for Microwave Power Transmission

Abstract

This article introduces an overview of a rectifyingantenna (rectenna) circuit topology for microwave power transmission system. Specially,a rectenna based on a microstrip patch antenna and a microwave rectifier at 2.45GHz were designed and fabricated. The antenna’s return loss is achieved of -26 dB at 2.45GHz. The microwave to DC conversion efficiency of the rectenna was measured as 40.1% with 24 dBm input power and 220 Ωload. The design and simulated results were carried out by the microwave engineering professional design software, known as ADS2009 package. All design and simulationresults will be reported
