Help with Koch Fractal Monopole Simulation on HFSS

Hi Everyone,

I could really use some help. I'm new to HFSS and I'm trying to simulate a quad fractal monopole antenna system. My issue is that I am not sure what is the best way to excite the system. Lumped port? Wave Port? Other?
I'm attaching my HFSS a file so you can take a look at it.

Can anyone help me please?

thanks
