Modify X-NUCLEO-NFC08A1 to support commercial NFC antenna

Hello,

I am currently trying to modify the schematic of the X-NUCLEO-NFC08A1 to support the connection of any commercial NFC antenna.

From my understanding, I need to add a standard RF connector (SMA/U.FL/IPEX, etc.). Since commercial antennas are typically designed with a 50-ohm impedance, I believe the matching network may need to be redesigned as well. However, I am new to PCB and RF design, so I am not very experienced yet.

I would greatly appreciate any guidance or advice on the basic steps to achieve this. If there are any relevant reference documents or application notes, I would be very thankful if you could share them.

Thank you!
