摘　　要：本文介绍了适用于无线传感器网络的、能进行无线输能的整流天线和能进行无线定位的时间反演算法。适用于无线传感器网络的整流天线要求紧凑的天线结构,高效的微波能量到直流电量的转换效率以及较高的入射波频率。利用时间反演算法的时—空聚焦特性,可解决无线传感器网络中节点无线定位问题,以提高整流天线的效率。This paper describes the principle and latest progress of the rectennas and the time-reversal algorithm. Rectenna in the wireless sensor network can be utilized to transmit power, moreover time reversal algorithm can be used for wireless orientation in the wireless sensor network. Rectenna in wireless sensor network needs compact antenna configuration, high conversion efficiency which RF power is converted into DC power, high incident frequency. The time-space focusing characteristic from time reversal algorithm can be utilized to solve wireless orientation problem for the nodes in wireless sensor network so as to enhancing efficiency of rectenna.
