摘要

在这封信中，我们提出了一种为无线电力传输量身定制的紧凑，高效的全极化接收整流天线的创新设计。该天线采用天线阻抗与整流阻抗直接共轭匹配的方式，将一个天线与两个整流单元集成在一起。这种方法消除了外部阻抗匹配网络的必要性，从而减小了整流天线的整体尺寸。虚拟地概念的实现简化了整流器输出滤波器的设计。这种低轮廓天线的设计工作频率为2.45 GHz，在所有偏振角度上都具有很高的转换效率。测量到的RF-to-DC效率在所有偏振角下都超过63%，峰值效率达到82.2%。

Compact High-Efficiency All-Polarization Rectenna for Wireless Power Transmission

In this letter, we present an innovative design for a compact, high-efficiency all-polarization receiving rectenna tailored for wireless power transmission. This rectenna, which integrates an antenna with two same rectifier units, employs direct conjugate matching of antenna impedance to rectifier impedance. This approach eliminates the necessity for an external impedance-matching network, thereby reducing the overall dimensions of the rectenna. The implementation of virtual ground concept streamlines the design of the rectifier's output filter. The low-profile antenna, engineered for operation at 2.45 GHz, demonstrates high conversion efficiency across all polarization angles. The measured RF-to-DC efficiency exceeds 63% for all polarization angles, achieving a peak efficiency of 82.2%.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
