NFC Antenna Design

Hi,

Regarding to the NFC Antenna with the 28x30.5mm dimensions.

https://www.seeedstudio.com/NFC-Antenna-p-1805.html

Could you please share the Gerber file? Later I also would like to design customized Antenna in Circular shape with the use of Grove NFC PN532 Eval board & the receiver tag of NTAG215.

Could you also share a reference document or Circular Antenna Gerber file to design.

Thanks
