Optimalization of microstrip antenna model - bad param calculation

I have probleme with modeling our microwave antena model.
Modeled parameters (S11, S21 VSWR) is far from the reality. I attached files our antenna in real and our measurement microwave analyser (there S22 = S11 (middle), S21 = S32 (bottom), VSWR (upper)). This simulation isnt usefull for our experiment.

(Its because size is largen than max. size of attached file)
Detail of experiment:
We stimulate diamond (that is placed on the omega shape) sample with microwave (sweep 2-4GHz). Input source have 1.8V and its connected to antena by coaxial cable and SMA connectors. On one site there is stimulation by microwave, on second there is 50 ohm terminal.
Can you please somebody fix my model for making better S parameters? I have a issue that this can be done by wrong use of input and output ports on modele but I have no idea how to fix it.
Thanks a lot
