CST Port Help

Hello
I'm trying to simulate the antenna in the link below on CST: http://opensiuc.lib.siu.edu/cgi/view...text=ece_confs
The dimensions are all the same and the excitation source is a 10 ohm discrete port with a lumped capcacitor of 1.16 pf( for the reactance). I think this is where the problem is.
I attached the file along. Any Help is greatly appreciated.

Anyone please, Been trying it still but can't get it too work, or if i can be pointed to some similar tutorials that would be great too.
