NRF52833 TRACE ANTENNA ISSUE

[Tariq]

Hi.

I have designed a node with NRF52833 with +8db power antenna.But i got some issue in signal transmission over 1km range.Please review my layout and matching circuit.Matching network, Layout & Gerber file of my pcb node is attached below.

You need to share the files, ideally as PDF or/and GERBER file, but Kicad and Altium is also ok. 

Seems the files did not attach correctly so please try again. You can put everything in a zip\compressed folder and share here. 

But i got some issue in signal transmission over 1km range.

What protocol are you using? 


Also best way to get the most performance is to have the radio matching tuned and have the antenna tuned. 


Regards,
Jonathan
