I simulated GCPW, the working frequency band is 1-110GHz, the length is 20mm, and the GCPW loss S21 is very poor; may I make a mistake in my simulation.
Does GCPW have vias? Should the ground on both sides of the upper center conductor be connected to the ground on the lower GND? In the paper, GCPW has no metal pillars.
Thanks.
