This article presents the design, simulation, fabrication, and measurement of a compact power‐harvesting circuit. A quadrature hybrid coupler is used for this harvesting circuit because of its advantageous matching, high isolation, and lossless characteristic. It properly feeds the bridge rectifier, combining the signals received with two antennas. The bridge rectifier component is a turnout full‐wave rectification from a two‐wire alternative current input. The measurements found output power to be −25.5 dBm using a 5 KΩ load resistor, at 5 GHz. The transmitter antenna input power level is 7 dBm, at 50 cm distance. Both results of the Friis Equation and the measurements are in agreement. According to the results, the power‐harvesting circuit can operate for wireless local area network sensor applications.

使用正交混合耦合器的天线整流器，用于功率收集应用

本文介绍了紧凑型功率收集电路的设计，仿真，制造和测量。正交混合耦合器用于此采集电路，因为它具有有利的匹配，高隔离度和无损特性。它正确地给桥式整流器馈电，将两个天线接收到的信号合并在一起。桥式整流器组件是来自两线交流电流输入的道岔全波整流器。测量结果表明，使用5KΩ负载电阻在5 GHz下的输出功率为−25.5 dBm。发射机天线的输入功率电平在50厘米距离处为7 dBm。Friis方程的结果与测量结果一致。根据结果​​，功率收集电路可用于无线局域网传感器应用。
