Hi Irfan

If you don't have ground on any of the layers below the matching network or RF section, I don't know how this will affect certification. It might be ok but I have never tested this. 

In the reply from Kaja, she say the inner layers should be removed, not all layers. There should be ground on at least one layer. 

cheers,

Ketil
