-There is no Top-to-GND via. Place stitching vias where possible.
As another member said above:
For both cases the GND plane really needs to be solid: No cut underneath your "signal trace", no other signals underneath your signal trace.
Solid as shown in your last picture of post#1.

Hi,
In order to keep traces thinner and to avoid complexity, I have designed a 4-layer PCB with following stack-up:
1 - Signal
2- Ground
3 - 5V
4 - Signal
The height between first 2-layers i.e. RF components and ground is 0.2104mm which gives approximately 0.3mm trace width for 50ohm match...
Thanks for replying.
Sorry, I meant 0.3mm trace width.
It is one of my concerns that should I have top ground fill plane or not. Yes, you are right it will make coplanar topology. So, you suggest, I should remove ground plane from top and use via holes on pads to connect them ground. Along with...
Hi,
I am an amateur in the field of PCB design and my experience includes multiple PCBs design of basic digital electronics and STM microcontrollers etc. I have got them manufactured by JLCPCB and they worked, successfully. This is my first basic RF PCB designed in KiCad and requires some...
