My simulation in HFSS is not real, I need help

Hello All,

I′ve designed an inductor antenna, and I want to get the radiation pattern between 0.5 and 1.5 GHz.

My results at HFSS does not fit with the real mesurements. Can you review my project and tell me where is the error?

I′ve lost some days with that project learning with the tutorials, but I need someone with experience with HFSS.

Thanks in advance.
