Research and Modeling of Flexible Bending of UHF RFID Tags

Simulation of RFID tag AZ-9654 with known topology was carried out. To study the electrodynamic parameters, several states of the tag were simulated: basic, as well as with flexible bends (on cylindrical and rectangular surfaces). The results of the study show changes in the electrodynamic characteristics (radiation pattern, S11 parameter, VSWR) with flexible deformations of the relative base state and the declared characteristics. In turn, the results of the study make it possible to analyze changes in electrodynamic parameters (including negative ones) and take them into account when designing antennas for RFID tags.
