Abstract

Recently introduced passive wireless strain sensors based on microstrip patch antennas have shown great potential for reliable health and usage monitoring in aerospace and civil industries. However, the wireless interrogation range of these sensors is limited to few centimeters, which restricts their practical application. This paper presents an investigation on the effect of circular microstrip patch antenna (CMPA) design on the quality factor and the maximum practical wireless reading range of the sensor. The results reveal that by using appropriate substrate materials the interrogation distance of the CMPA sensor can be increased four-fold, from the previously reported 5 to 20 cm, thus improving considerably the viability of this type of wireless sensors for strain measurement and damage detection.

摘要

最近推出的基于微带贴片天线的无源无线应变传感器在航空航天和民用工业的可靠健康与使用监测方面显示出了巨大潜力。然而，这些传感器的无线询问范围限制在几厘米，这限制了它们的实际应用。本文研究了圆形微带贴片天线（CMPA）设计对传感器品质因数和最大实际无线读取范围的影响。结果表明，通过使用合适的基板材料，CMPA传感器的询问距离可以增加四倍，从之前报道的5厘米增加到20厘米，从而大大提高了这类无线传感器用于应变测量和损伤检测的可行性。
