Simulating CPW in HFSS to find the Z0 of the line

I simulate CPW/grounded CPW on HFSS,
my target is to find the Z0 of the line.

do I need to calculate this thru S-Parameters / Z-Parameters,

or is there any shortcut ?

There is a short cut, there are equations that you can get from Pozar's Microwave engineering book or you can download the free program AppCad which will calculate Grounded CPW characteristic impedance and with out Ground (it does several other things as well.)

Hello,

Yes, S- or Z or Y Parameters are the solution you can do the CPW analysis using Method of Moments (MoM) ElectroMagnetic Simulator such as Sonnet...

To find the Z0 of the CPW Transmission line, as to my knowledge, you can set the excitation(wave port) non-renormalization in the post processing. And you see the result of re(Z0(P1)), which is the characteristic impedance of the line.

CAN ANYONE HELP ME GETTING FREE OR STUDENT VERSION OF HFSS?
OR TELL ME ANY OTHER SOFTWARE FOR SIMULATING WAVEGUIDE?
