CST - wave port for slotted line - How to define it?

Hi everyone,

Is there anybody help me how define a port for slotted line in CST?
I need this information so much.

thanks in advance!

the width of the waveguide port should be 2W upto 3W. where W is the width of the slot line.
the height of the port should be w for ungrounded slot line and W/2 above the slot line for the grounded slot line.
hope this helps u

Oh, It's the same to CPW.

Thanks for your time, Shahid78.
