Calculation of the equivalente mutual impedance in complex HF RFID systems

Abstract : In this work the improvement of HF RFID detection is obtained by the addition of small resonator in the reader coil. In conventional RFID system, the link between the reader and the tag coils is the mutual inductance, the added resonator is magnetically coupled with the reader coil, and then the link is expressed by the mutual impedance. Theoretical calculation of the equivalent mutual impedance of such system is reported and validated by comparison with HFSS simulation and measures.
