Abstract :
This paper describes a systematic design procedure of coils for optimal operating range of magnetically-coupled radio frequency identification (RFID) system. Given the sensitivities of both RFID reader and tag, the proposed design procedure, theoretically, calculates the inductance values and dimensions of both reader and tag coils, and predicts the corresponding optimal operating distance. Two design examples for both 125 kHz and 13.56 MHz RFID systems using typical sensitivity values are given to illustrate the proposed design procedure
