Layout Chip antenna nRF24L01+

[Alexandre]

Dear,

Please, could help me ?

My knowledge in RF is basic.

I am developing a system to use 8 RF channels (nRF24L01 +) simultaneously. I'm using Balum 2450BM14A0002 and antenna 2450AT18D0100 ( both Johanson). The board layout was as seen in the figure.

I attached the circuit containing all 8 channels.

My question is: This is a good layout or need to modify the layout? Any modification is necessary?

The two capacitors and the resistor close to the antenna is to improve tunning, but I dont know how calcule the capacitor and resistor value. It was recomended to me for a friend. This is a precaution.

This layout will work correctly? Or do I have problems with the signal? I'm considering creating a drilled area under the antenna.

I appreciate all the help. Thank you

Alexandre

I believe this question is better suited for MyPage support portal on nordicsemi.com.

Please include schematics (pdf format), layout files (gerber files) and "bill of material".

You don't need to delete the question, but please add a case on MyPage.
