I have this antenna model AH316M245001-T.
RF signal will be routed using CPW with ground vias. RF freq. is 2.4Ghz, 50ohm line.
I can't find this information about CPW:
- What are the recommended via dimensions and distance between vias at this frequency?
- How should I connect CPW grounds, in particular, should I avoid connecting components to this ground? Should I create a via "wall" all around?
Would something like this be correct?
Or should this ground go all around the PCB board?

I have been using these general guidelines in transmission line design:
You should calculate your wavelength carefully as it depends on the dielectric you are using.
Having said that, for 2.4GHz I usually don't follow the last guidelines and so far had no issues with that.
