[lgs]

Hi Team,

I am trying to develop my PCB based on nrf52840 chips. Now I want to know the type of ant(not NFC) used in nrf52840DK as my reference.

Could you help me?

With best regards,

Hi Gaosheng,

The antenna used on the nRF52840DK is a monopole antenna. We have a white paper available on this type of antenna:

The hardware design files for the nRF52840DK is also available for download:
