Hello,
The back of the NFC antenna pattern in the photo below is designed with a ground pattern. Could you advise on the characteristics this might entail?
Thank you.
The chip in the above picture is an NXP chip, but it's not the one we use in our devices.
Thank you for your interest.
Hello theo-choi,
I know that some customers used similar patterns for better EMI behavior.

Hello @theo-choi
Could you share the exact type of the IC what you are using? Maybe, some Demo design can be recommended to you for reference.
Connecting the center of the antenna pattern to GND improves the characteristics against power noise.
