A Novel 5.8GHz Circularly Polarized Rectenna for Microwave Power Transmission

This paper reports a novel circularly polarized rectenna designed and measured at 5.8 GHz for application involving microwave power transmission (WPT). A truncated corner square patch microstrip antenna used for the rectenna was developed. The axial ratio achieved was 0.3 dB at 5.82 GHz. A silicon Schottky barrier diode is employed as the rectifying device. Measured conversion efficiency results of the rectenna proved that the rectenna is suitable for component of the WPT system.
