Hi，

The design I'm using now is that trf7962a is inside the antenna, with the chip on the front and the antenna coil on the back. Is there any problem with this design? Will it affect the antenna signal?

If I can design this way, what other problems should you pay attention to?

Hi,

If you can verify you have correct TX output output power and correct impedance matching to 50ohm then I think you should be fine. Avoid crossing of digital lines under RF signal lines as much as possible. If unavoidable, use 90 degree crossings to minimize coupling of the lines.

Please refer to the best practices on RFID Layout Design Guideline.
