Petal shaped semicircular resonator for RFID tags

Effective utilization of resonating structure in RFID tags is studied in this paper. Petal shaped semicircular resonating structure is direct coupled with the strip line. For enhanceing the characteristics, the single base resonator is modified. Useing ANSYS HFSS the resonator structure is optimized for performance analysis. Validation of the optimized resonator is done, both the measured and simulated results are found to be in compromise with each other.
