cpw ansoft designer

The port setup for cpw located on the inifinite ground plane is very easy, for there is coplanar port in designer,but for a cpw with finite ground is not very easy, one should setup reference ground for the source port. Is there anyone who ever had such a experience?

use microwave port covering the whole region of the CPW port.

Thanks for your reply red-sun.Could you explain the port setup method in detail, for example ,by using a picture.

Why?Is there anyone can help me or give some advice?

There is a ppt on the website of ansoft company, which explained the setting of CPW port.

I need this ppt for setting my ports....could you give me ?

Hi fishyxl,

I think that ppt in Ansoft website is for setting CPW ports in HFSS, not in Ansoft Designer.
