hello,
i wish to design a coplanar stripline on a dielectric substrate with HFSS and wants to study both odd and even field configurations. Since i am new to Asoft HFSS i would like somebody to please help me out with the excitations and other guidelines. I shall be highly obliged.
Thanks in advance.

please suggest me on the waveport etc. front..thanks again.
Do you have a solution?
I'm trying the simulation of a CPS in CST Microwave studio. I want to get the line impedance.
I have tried with waveguide and lumped port but I don't get the expected results (I'm even not sure where I can find the line impedance value).
An analytic calculation of a CPS can be found in **broken link removed**
thank you for your reply. the paper was indeed helpful. but what i want to know is, whether or not the dimensions of CPS ie width of slot and strips, dependent on frequency? if yes, then what all are tyhe relations?
please help.
I think the Z0 of a CPS should be independent of the frequency.
If you look on the synthesis formulas in the paper there is no frequency involved.
Also note the paper assumes a loss free substrate. Probably with a lossy substrate Z0 depends on frequency.
OK. Nw when i simulated CPS considering one dimension, i got few "dips" in the S11 and S21 curves, even though the circuit is not a radiating one, neither it should signify the resonance condition as there is no cavity.
any help please.
