摘要/Abstract

摘要： 将整流天线单元等效为一个直流源和负载的串联, 以此提出了整流天线串/并联组阵等效模型, 得到了整流天线的组阵形式及最佳负载与阵元个数之间的关系. 利用所设计的低功率密度应用整流天线单元, 通过ADS 软件仿真了二元并联阵, 并通过实验测试了二元串联阵与二元并联阵. 结果显示, 并联阵的仿真与实验结果及串联阵的实验结果均与组阵模型基本吻合, 从而验证了整流天线组阵模型的有效性. 提出了多元组阵的可行性方案, 为大规模阵列设计提供指导.

Abstract: A rectenna is equivalent to a series circuit of a DC power and a load. Equivalent models of series and parallel of rectenna arrays are proposed, so that the relationship of the optimum loads and the element numbers for the series and parallel rectenna arrays are obtained. Using a rectenna element with low power density applications, the two-element parallel array is analyzed with ADS software. The two-element arrays in series and in parallel are measured. Simulated and measured results of the parallel array and measured results of the series array are approximately in accordance with their equivalent models, showing effectiveness of the equivalent models. Suggestions are given for designing large rectenna arrays.

Key words: conversion efficiency, equivalent model, rectenna, rectenna arrays, rectifying circuit
