NFC antenna design for PN7462

Hi guys,

I'm designing my custom PCB with PN7462 chip on it. I need PN7462 for contactless NFC interface. From the UM10883 document, I realized how to design EMC filter and antenna matching circuitry (pages 17, 18). What is missing in that document is the design of the antenna coil. As far as I know, it is rectangular, 2 turn 65mm x 65mm coil. However, there are no exact dimensions.

Is there anyone of you who is able to help me design that antenna coil for PN7462?

Thank you very much in advance for your time and effort.

Sincerely,

Bojan.
