摘要

本文介绍了一种小型整流器与低轮廓天线集成，用于采集2.4 GHz射频能量。所提出的射频能量收集整流器实现射频到直流(RF到直流)功率转换效率(PCE)高达71%。此外，整流器达到5.022 V直流输出电压以及45 kΩ负载端子与20 dBm。此外，所选天线原型作为接收器工作，以便在使用所提出的电路将RF信号转换为直流电压之前收集RF信号。与其他先进的整流器相比，该系统的特点使其成为低功耗无线通信系统的良好候选者。

A developed Rectenna for Wireless Energy Harvesting System with High Efficiency

A compact rectifier integrated with a low-profile antenna for harvest radio frequency (RF) energy at 2.4 GHz is presented and experimented with in this paper. The proposed RF energy harvesting rectifier achieves RF-to-dc (RF to direct current) power conversion efficiency (PCE) up to 71%. Additionally, the rectifier attained 5.022 V DC output voltage along with a 45 kΩ load terminal with 20 dBm. Besides, the selected antenna prototype works as a receiver in order to collect the RF signal prior to converting it to DC voltage using the proposed circuit. The features of this system qualify it to be a good candidate for low-powered wireless communication systems as compares to the other state-of-the-art rectifier.
