摘要

本文提出了一种用于微波能量传输的圆极化整流天线，它由宽带基底集成波导（SIW）天线和整流电路组成。在 SIW 天线上加载了一个介质谐振器，从而提高了阻抗带宽。通过对矩形贴片的对角线进行倒角，实现了圆极化。采用了两段微带分支，以在宽带工作中实现良好的阻抗匹配。测量结果表明，在 22.9% 的相对带宽（29-36.5 GHz）范围内，拟议的整流天线具有良好的阻抗性能（|S11| < -10 dB）和较高的射频-直流转换效率（>50 %）。输入功率为 18 dBm 时，最大转换效率为 67.5%。

A broadband Millimeter-Wave rectenna using substrate Integrated Waveguide

In this paper, a circularly polarized rectenna is proposed for microwave energy transmission, which is composed of a broadband Substrate Integrated Waveguide (SIW) antenna and a rectifier circuit. A dielectric resonator is loaded on the SIW antenna, enhancing the impedance bandwidth. Circular polarization is achieved by chamfering the diagonal of the rectangular patch. Two sections of microstrip branches are employed for good impedance matching over the broadband operation. Measured results show that the proposed rectenna has a good impedance performance (|S₁₁| < −10 dB) and high RF-DC conversion efficiency (>50 %) over a relative bandwidth of 22.9 % (29–36.5 GHz). The maximum conversion efficiency of 67.5 % is realized at the input power of 18 dBm.
