Hi

We generally don't recommend specific chip antennas, as there are so incredibly many of them available from various manufacturers. I suggest you go to DigiKey or Mouser, or your preferred component provider and search for Bluetooth antenna. Taiyo Yuden, Laird, and Johanson Technology are some of the more common chip antenna providers.

As for PCB reference layout and reference schematics for the nRF52840, please check out our reference circuitry page on the Infocenter, as well as our PCB design guidelines application notes here.

Best regards,

Simon
