Hi All,

I am trying to tune an RFID antenna matching circuit, and I need to figure out the values of C40, C41, C42, C43 I am trying to use the excel attached
Matching Calculator

The Antennas Inductance is 5.1uH and 0.5 Ohms
The frequency of the circuit is 13.56 MHz

See the circuit below:

The circuit doesn't need to be 100% tuned at first, but it should at least work...
Is there any information I am missing?
