Hi,

I need spice/spectre model of 13.56MHz antenna coil for RFID applications.

I have used a voltage source and a series resonance circuit for the reader end and a parallel resonant circuit at the tag end. Since energy transfer takes place through electro magnetic induction, i have used coupling coeff of 0.7. Have attached the circuit I designed.

please let me know where I am wrong as I didn't get expected result.

 

Hello,

Have a look at the following PDF:
