Hello Guys,

How to calculate resonant frequency for RFID?
How inductor and capacitor values are set? How Q factor affects antenna performance and RFID detection for card? For good performance of 125KHz LF and 13.56Mhz RF what should be the Q factor value? Please provide suggestion or document for these calculation...
