To do coplanar waveguide

Hello everyone,
I need to incorporate coplanar guides into my design.
I did the dimension calculations, it’s OK.
could you tell me what is the right method to integrate them into the PCB, because apart from doing it manually, I don’t know how to dimension the isolation distance between the trace and the ground onTOP side. Also to place vias all along the trace.
Thank you

Generally, netclass clearances are what you’re looking for.
I’ve also needed to tighten the clearances to reach compact components.
Check this old thread: Is it possible to force zone to clearance lower than Netclass clearance?

@fred4u Thank you Michal, I test this week.
