hfss directional

Hello,

I tried to design the directional coupler using HFSS. My design is to verify the effect depending on coupling factor. Is there anyone who knew the method to get coupling factor (C) using HFSS?

If somebody give me a tip or method, I really appreciate it..

i think you can use ansoft MAXWELL 2d to get coupling factor. also you can email to me .

i was designed a 2-18GHz coupler with this method . i think it's good to solve almost directional coupler.
