Chipless RFID strain sensors: A novel feasibility analysis in terms of conventional patch antennas

This paper focuses on the design and feasibility analysis of conventional microstrip patch antennas as chipless RFID strain sensors. Three sensing antennas with different substrates are designed and their structural deformation due to different types of applied strain is theoretically analyzed. These theoretical deformation results are used to calculate the corresponding resonance frequency and quality factor deviation to determine the maximum amount of stress the antennas can tolerate. Thus a novel analysis is presented to determine the acceptability of the designed antennas as strain sensors.
