RF PCB design
It is also important to take great care on the dielectric coefficient of the PCB and the thickness of the copper .
It is significant if the design frequency is large, say >900MHz.
Also, I found the green paint on the PCB will also affect the frequency responses in certain level.
I remember, I have a 2.4GHz antenna PCB designed using microstrip line, the impedance of the antenna will not the same for the presence of those paints ont the microstrip lines.
