HELP NEEDED ON CPW FED FRACTAL ANTENNA

[jcp_123]

coplanar waveguide fed for antenna

I am new to working in HFSS and am really confused about using lumped port or wave port...

I have designed one using a lumped port and am getting quite good results for it...but I don't know whether the assignment of the port is correct or not.

So I tried using wave port for the design, but the s11 results are going awfully wrong... pl can anybody help me??

I am attaching both the hfss files... PLEASE have a look at them and tell me where am i going wrong

I know there are a lot of experts out there so waiting for a positive reply...
