一种矩形微带整流天线的研究与设计鄢

内容简介：微波整流是无线输电中的一个重要环节，为完成微波能量的接收，设计了一个结构简单、整流效率高的贴片矩形微带整流天线，此整流天线包括矩形微带天线、输入低通滤波器、整流二极管及输出滤波器。该整流天线的面积小，配合其他装置组成的微波输电系统，可方便地应用于传统有线输电无法应用的场合。通过系统仿真以及实验测试，验证了整流天线的可行性及其高效率，实际测量后计算出整流效率高达63.4%。

Abstract：Microwave rectification is a crucial part of power wireless transmission . To complete the receiving of microwave ener-gy , it designed a rectangular microstrip patch rectifying antenna with simple structure and high efficiency rectification , which con-tains a rectangular microstrip antenna , the input low pass filter , rectifier diode , and the output filter . Rectifying antenna area is small , combined with other devices could form the microwave power transmission system , which can be easily applied to occasions where traditional wired transmission cannot be used . It was verified the feasibility and high efficiency by the system simulation and lab test , and after actually measured could calculate the rectifier efficiency is as high as 63 . 4%.
