Abstract

A dual-polarized rectangular slot rectenna is proposed for ambient RF energy harvesting. It is designed in a compact size of 55×55×1.0 mm3 and operates in a wideband operation between 1.7 to 2.7 GHz. The antenna has a two-port structure, which is fed using perpendicular CPW and microstrip line, respectively. To maintain both the adaptive impedance tuning and the adaptive power flow capability, the rectenna utilizes a novel rectifier topology in which two shunt diodes are used between the DC block capacitor and the series diode. The simulation results show that RF-DC conversion efficiency is greater 40% within the frequency band of interested at -3.0 dBm received power.
