Antenna Design

Hi Dialog,
I am designing a pcb for da1483 using Inverted F antenna design(Full sized IFA) as specified in the Application note AN-B-027.I am using Kicad software for designing.I have successfully imported the dxf files in F.paste ,Bpaste layer and have placed via to interconnect both the top,bottom layers.I want to ask that ,do we need to import antenna as copper trace or is it ok if we use it directly in F.paste layer(solder mask layer?
Thank You.

Hi Sir,

Hi Sir,

Here is a feedback after check with our system desgin team:

天线必须铜,直线部分of it must be printed in copper on the top and bottom layer.

It’s advised to cover the copper traces with solder-mask.

The top- and bottom-copper must be stitched together using vias. This 2-sided design makes radiation efficiency better.

The bent feed ‘arm’ is on the top layer only (or on the bottom layer only: it must be at the same layer as where the BLE chip is).

I added 2 photos to make it clear. From 68x Pro-Kit daughterboard.

Top-side (681 side)

see attached

Bottom-side.

The top and bottom side are connected through multiple vias.

The copper traces are covered with solder-mask.
