Ceramic antenna placed externally to PCB

Other Parts Discussed in Thread: CC3100

Hi all,

I want to ask if there is an raccomanded or adviced layout to place antenna externally to PCB.

Something like this:

It can be equally good to TI CC3100 pcb layout with signal quality and certifications?

In this way I can avoid the use of PCB void, but I can't connect antenna pins to ground plane(or I can wiring ground near antenna, but I think it will be ugly).

Should I connect each antenna pin to ground?

Thank you!
