De-embeding an arced feed line Using wave port in HFSS !

Hi everybody,

I have a micro strip loop resonator with a feed line goes to the middle of the loop (my feed line is curved and shaping an arc at some part of my structure).
I know how to use wave port and here I only have one single wave port. My problem is with the length I need to de-embed!


I basically set my wave port on the air box (Radiation box) and stretched my feed line to the wave port location, then I de-embedded that added length of the feed line. until here everything looks good, then I want to de-embed the curved part of my feed line and here comes the problem. When I de-embed for the actual length of the feed line (including the curved part)towards my structure in order to remove the effect of my full feed line, HFSS does not see my curved feed line. Instead it considers the entire length to be a straight line.

Q. Is there any way I can de-embed an arc (curved feed line) using HFSS?
If any one have tried a similar thing, please I need some help here.

Unfortunately changing my design is not an option.

Thanks guys

It would probably best to assume some effective de-embedding length, for example the average length of the curve.
