Hi,

We are developing nRF52840 based design with PCB antenna.

Please review the Schematic and PCB file.

Hi,

Thanks for the review and provide the feed back to us.

I have a question on "1 You should remove he cut outs on the inner layers. You need to have some shielding under the RF section and the inner ground layer can do that. "

Before few days i had share the other design with you and that time you had suggest below 

"6. On PCBs with more than two layers, put a keep-out area on the inner layers directly below the antenna matching circuitry (components between device pin ANT and the antenna) to reduce the stray capacitances that influence RF performance.

Suggest by Kaja "

You can check my previous post "

Review schematic and PCB layout.

So please let me know the difference in this 02 comments.
