Recommended External NFC antenna for nRF52840 Case ID: 322538

[Dhruvit]

continue from previous closed ticket Case ID: 322538

here i have recommended production file of nfc antenna from nordic semiconductor but the Gerber file does not include some confirmation which i get on jlc pcb while verification  

the above marked field is need to be verified by designed stackup and tested value but i haven't, for that i need assistance from expert "is this auto adapted values are right ?"

and in our another model i need to design nfc on pcb, where this reference design here, is key

here i need required impedance and recommended stackup for on board pcb nfc design.

thanks & regards
