Abstract
A polarization reconfigurable rectenna, which consists of a polarization reconfigurable planar monopole antenna and a planar rectifying circuit, is proposed for microwave power transmission (MPT). The planar monopole is designed with one linear polarization (LP) and two circular polarizations (CPs). The rectifying circuit is connected to the antenna with a 50 Ohm microstrip line. The rectenna can harvest the RF power from 5.07 GHz to 5.86 GHz and convert it to DC power efficiently, exhibiting conversion efficiency from 40.2 % to 57.4 % with input power of 16.5 dBm. Simulated results are confirmed through the experiment.
