I've been heavily researching the dark magic of RF antennas and resonance matching for NFC communication. The IC I've chosen is the popular PN532 and the antenna is a Taoglas FXR.2020.52.0075X.A.dg.
I've attempted to use a T-Match circuit for this application. Can anyone else who is slightly more wizard-like than me confirm my calculations or spot any glaring issues?
My previous design utilised a 25pf cap on each TX line to ground and 560nh inductors with a 2.7K R2 on the RX line. This worked albeit with a <1mm range. I've now tried lowering the inductance and using only one 120pF shunt cap.
TIA!
