Abstract

With the recent surge in popularity of the Internet of Things (IoT), there also has been a notable increase in research on wirelessly charging IoT enabled electronic devices. Millimeter-wave retrodirective power beaming has recently emerged as a suitable candidate for wirelessly charging small electronic devices. In this paper, we propose and demonstrate a millimeter-wave power beaming concept applicable to IoT ecosystem. The proposed system incorporates a Rotman lens retrodirective beamformer as a Tx unit. To demonstrate the retrodirective power beaming, a Rotman lens beamformer on a waveguide platform is designed to operate at Ka-band. The proposed Rotman lens operates with seven beam ports capable of radiating seven beams within $\pm$30° steering range. On the receiving end, a rectenna consisting of a patch array and rectifier is designed. We then conducted an end-to-end power beaming experiment as proof of concept, where the results demonstrate the capability of the proposed system as a retrodirective millimeter-wave power beaming system.
适用于小型电子设备的毫米波反向无线电力传输
随着最近物联网(IoT)的普及,对支持物联网的无线充电电子设备的研究也显著增加。最近,毫米波反向能量束成为小型电子设备无线充电的合适选择。在本文中,我们提出并演示了适用于物联网生态系统的毫米波功率光束概念。所提出的系统包含一个罗特曼透镜反向定向波束变换器作为Tx单元。为了演示反向功率波束,在波导平台上设计了一个在ka波段工作的罗特曼透镜波束形成器。拟议的罗特曼透镜操作有七个光束端口,能够在$\pm$30°转向范围内辐射七个光束。在接收端,设计了由贴片阵列和整流器组成的整流天线。然后,我们进行了端到端功率波束实验作为概念验证,结果证明了所提出的系统作为反向毫米波功率波束系统的能力。
