Experimental Study on Dual-Band Differential Rectenna with Stacked Antenna Configuration

摘要

In this paper, a novel dual-band differential rectenna is proposed and its performance is experimentally evaluated. The proposed rectenna has a simple structure in which 2.45- and 5.8-GHz band microstrip antennas are stacked. The conversion efficiency under 0.29-W/m^{2 power density was 63.6% and 31.1% at 2.5 and 5.95 GHz, respectively.}
