摘要

本文介绍了一种用于机械健康监测的无线供电应变遥测仪。遥测仪集成了一个调谐为2.4 GHz的整流天线。该整流天线由谐振印刷偶极子天线、微带传输线滤波器和市售高频二极管组成。实验结果表明,当增益为15 dB的10 w八木发射机照射在2.5 m以上的距离上时,该天线能够向无线遥测仪提供8 mW的直流功率。

Remotely powered wireless strain telemeter
This paper presents a wirelessly powered strain telemeter for mechanical health monitoring applications. The telemter is integrated with a rectenna tuned at 2.4 GHz. The rectenna is comprised by a resonant printed dipole antenna, microstrip transmission line filters and commercially available high-frequency diodes. The experimental results demonstrate that the rectenna is able to deliver 8 mW of DC power to the wireless telemeter when illuminated by a 10-W Yagi transmitter with a gain of 15 dB placed at a distance of over 2.5 m.
