基于RFID短路短截线贴片天线的无源无线应变传感及其小型化研究
Research on passive wireless strain sensing using RFID short-circuit stub patch antenna and its miniaturization design
摘要
Abstract
To address the issues of complex wiring,energy dependence,and high maintenance costs associ-ated with traditional sensors,a passive wireless strain sensing method based on radio frequency identification(RFID)technology and its miniaturization design were proposed.The RFID short-circuit stub patch antenna strain sensor was designed with the aid of HFSS software simulation.Miniaturization was achieved through meandering slot and short-circuit loading techniques.Multiphysics simulation analysis confirmed a linear cor-relation between the resonant frequency of the RFID sensor and the applied strain.Laboratory tests including directional performance tests,tensile strain tests,and bending strain tests were conducted.Results show that there exists a strong linear relationship between the resonant frequency and strain of the designed RFID patch antenna sensor.After miniaturization,the area of the sensor's patch antenna is only 66.4%of its original area,while a large wireless transmission distance is maintained.Compared with wired strain measurements,the RFID sensor exhibits smaller errors,verifying its applicability in practical structural health monitoring.关键词
