How to define port for coplanar stripline (CPS) in HFSS - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi, all,
I don't know how to define a corret port for coplanar stripline. From the tutorial, I know how to draw port for coupled microstrip lines, but CPS does not have a common back ground. How to draw the integration line for CPS?
Thanks in advance!
Lu

you could draw a square between the CPS lines (in same plane with the lines) and define your port in the center of that square

Hi, thank you for your reply. I guess what you suggested is a lump port. Is that correct? But I want to set up a Waveport so that I can see the field lines. Do you know how to set waveport for CPS line?
