Hello, thank you for your interest in our products.
Although we cannot share the Gerber files, I would like to recommend that please give it a try using our NFC Antenna design tool. This tool is intended as a starting point for your design. Also, please check our video series for antenna design that will definitely help you understand and apply these technics to your design.
The reason we recommend this road is that these calculations are very sensitive to the PCB properties and components used in the final design. For this reason, there is a great possibility of not getting the same antenna behavior even if our Gerber files are being used.
Please also check AN11019 and, AN11535 for additional guidance.
Best Regards,
Fabian
