Hi!
i made a custom PCB with the STM32WB1MMC. But Ii’m getting hardly 2 or 3 meters range.

Seems to be the same issue as 

 

but my device is right on the edge of the PCB.

My antenna keep put zone is a bit narrower than the reference board. Apart from this I not able to see what else could be wrong. Any pointers would be much appreciated. 
Thanks!
