Hello everyone,
I am simply simulating a quasi-TEM mode of a microstrip line in COMSOL. I got the results as expected, but there is one problem that when I change the length of microstrip, the transmission peak frequency shifts. Can anyone comment on this.
Parameters of line:-
Substrate thickness = 0.9 mm
Substrate relative epsilon = 9.9
Width of metal strip = 0.87
Length of dielectric and ground plate = 60mm (arbitrarly choosen)
Width of dielectric and ground plate= 8 mm (arbitrarly choosen)
I am exciting with the default lumped port of COMSOL at the starting of the transmission line.
