摘　　要：能够进行无线能量传输的整流天线技术是解决无线传感器网络能量供应问题的最佳技术手段。由此设计一种新型高效整流天线,采用将接收天线与整流二极管直接匹配的方法,在减小天线尺寸的同时提高了整流效率,在5.8 GHz下达到82.4%的转换效率,增加了整流天线的可串联性,能够更好地满足无线传感器网络的技术要求。Owing to the particularity of the wireless sensor network,the energy supply becomes a major technical problem that constraints its constant development.However,rectenna which is able to carry out the wireless power transmission is exactly in line with the technical features of the wireless sensor network.This paper designs a new type of rectenna.It employs a method of directly matching a rectifying circuit to a microstrip-patch antenna,as a result,the rectenna’s efficiency is improved and its dimension is reduced.This design realizes conversion efficiency of 82.4% at 5.8 GHz,so that it can satisfy the need of wireless sensor network better.
