Thank you ;)

Yes I know that putting parts under the antenna is not the best solution, but I did not have so much space on the PCB and I thought that the best RF emission is not the main criteria for a breakout board...

And yes it works :) 

  Are you sure? yes | no

Great looking breakout.  

My only critique is that the antenna part of the module should probably be as far from any metal parts as possible -- ground planes and components on the underside might influence the antenna / propagation.  Of course, if it works, it works.  :)

  Are you sure? yes | no
