We want to use the NFC feature of nrf52832 in read and write tag mode .Whats is the recommended antenna which has to be used along with the part number of the same.? please let us know if there are any antenna design specifications.

[Jaydev Borkar]

Also please let us know if there are any antenna design specifications. 

If  we use other antenna  for NFC is your certification valid or we need to re-certify  our  product for wireless

Compliance?

Any NFC antenna can technically be used with the nRF52832. A larger antenna will give higher reading distance. Also see this white paper: https://infocenter.nordicsemi.com/topic/nwp_026/WP/nwp_026/nWP_026_intro.html

You will always have to certify your design.
