NFC Class 6 Antenna Design

[davidcrosby]

Is there are reference design for a Class 6 antenna on standard 0.062" thick FR4 material? I have seen a Class 6 flex circuit reference design only.

Hello David Crosby:

You might want to take a look to the NTAG Antenna Design Guide ZIP package (which includes the AN11276 application note). The ZIP is available from the next link and it includes reference Class6 antennas:

NTAG I2C plus |Connected NFC Tag with I2C Interface|NXP

Basically the same design should work either on PCB or in a Flexible material, as long as there a no metal surfaces in the surroundings.

I hope this helps.

Best Regards!,
Jorge Gonzalez
