Help Needed W/ Conical Antenna in HFSS

I'm working on designing a wide-band (~75MHz-12+ GHz) conical antenna inside HFSS.

Would anyone know where I could find an example of something like this? I am finding that my models are compiling, but I am doing alot of stuff wrong; being that none of my radiation patterns, graphs, etc are showing any data, despite HFSS spitting out 40-80meg data files.

Any help is appreciated, thanks!
