Setups for doing CPW in HFSS or Momentum ?

I think it's quite important to assure the same voltage in both ground planes.

Hey Abuantenna,
You were right when you said you just draw a rectangle and assign a waveport to it. Just be dure to define the integration line from the CPW to the ground plane. Obviously, the port is going to be perpendicular to the plane of the CPW and you know the approximate sizes of the edges of the port.
I had another suggestion. Before you hit the analyze button for the whole structure, do simulate the ports first and see if the port impedances are what you need in your structure.

I've never used CST and hence wouldn't know what you're talking about!

Dear Ananth,

I am new for HFSS. I got one question for you. I got CPW line for both port 1 and port 2. So Should I draw the integration line just from signal to gnd for both ports? If I draw the waveport perpendicular to CPW plane, where my integration line should be? SHould that be on top of the rectangular of waveport where is intersect with the CPW line?

Also how to simulate the ports only?

If anyone else know the answer, please help me.

Thanks,

bbatud
