[Balu Varkala]

Hello,

This is first time to design the PCB antenna for nRF52840 BLE Chip. Can i use the nRF52840 DK Board HW layout for reference or should i use the USB dongle for nRF52840 HW file for reference. Please suggest....ASAP.

You can see our white paper.

That is very difficult to say, they will depend on the channel, environment, antenna efficiency, ect..
