摘要

This article presents a broadband circularly polarized (CP) rectifying antenna (rectenna) for microwave power transmission at 4.2-7.6 GHz, comprising a broadband CP antenna, and a rectifier circuit. The antenna consists of a standard Schiffman phase shifter and a pair of orthogonally positioned linearly polarized slot antennas with equal radiation strength. The rectifier circuit is composed of a microwave Si Schottky detector diode (HSMS-2862), a low-pass filter, a load resistor, and a ripple capacitor. Output dc voltage of 1.98 V over a 680 Ω load resistance and the maximum microwave-to-dc conversion efficiency of 81.6 % were measured when 34 dBm microwave power was transmitted at 5.6 GHz over a distance of 50 cm.
