Design and feasibility analysis of conventional planar antennas as chipless RFID strain sensors

This paper focuses on the design and feasibility analysis of conventional planar antennas as chipless RFID strain sensors. A number of printed monopole and dipole antennas are designed and their structural deformation due to different types of applied strain is theoretically analyzed. This theoretical deformation results are used to calculate the corresponding resonance frequency and quality factor deviation to determine the maximum amount of strain the antennas can handle. Thus a novel analysis is presented to determine the acceptability of the designed antennas as strain sensors.
