Abstract

This article presents a new planar microwave sensor for displacement measurements. The sensor is based on a modified triangular-shaped quarter-wavelength resonator that has the advantage of maintaining its linearity throughout the required displacement range due to its reduced ground capacitance when compared to conventional resonators. Designs of three different sensors are shown for displacement ranges of 4, 14, and 24 mm. Their figure of merit (FoM) is FoM =0.5 for the 4-mm sensor, 0.7 for the 14-mm sensor, and 0.97 for the 24-mm sensor. Moreover, the midrange sensor (14 mm) was manufactured to operate in a frequency range from 700 MHz to 2 GHz having an FoM =0.7. This sensor is operated using a vector network analyzer (VNA) and an alternative reflectometer board for onsite applications. The experimental values show errors of less than 4% when comparing the VNA and the reflectometer results.

高线性微波位移传感器

本文介绍了一种新型的平面微波位移传感器。该传感器基于改进的三角形四分之一波长谐振器，与传统谐振器相比，由于其接地电容降低，因此具有在所需位移范围内保持线性的优点。三种不同的传感器的设计显示位移范围为4,14和24毫米。它们的优点值（FoM）为：4mm传感器的FoM =0.5, 14mm传感器的FoM = 0.7, 24mm传感器的FoM = 0.97。此外，制造的中程传感器（14毫米）在700 MHz至2 GHz的频率范围内工作，FoM =0.7。该传感器使用矢量网络分析仪（VNA）和现场应用的替代反射计板进行操作。实验结果表明，VNA与反射计测量结果的误差小于4%。
