is there a way to add a black box to the HFSS

Hello,

I am designing an antenna, and I am trying to add a power amplifier to my design in order to get a CP antenna. My question is if there is a way to add a black box as a power divider in HFSS? since it is going to be easier to do the simulation.

Thanks,

I believe that you can't do this work in HFSS. But you can do it in Ansoft Designer by introducing a Data file with s3p representation.
