Antenna, HFSS port refinement error

Hi guys
I am designing a very simple dipole antenna using HFSS. However I am not able to run the analysis.
Here is the problem; As you see, there is a port refinement problem. I have added integral line and everything is connected and there is no gap between port and my dipole antenna.
Please help me by your instructive suggestions.

$begin 'ProfileGroup'

$end 'ProfileGroup'

which port did u used? lump port or wave port? if u used wave port an error will exist due to intersecting with radiation box.

Thanks for your response.
Actually I was using lumped port and I happened to find the problem. Around my metal was not filled with anything, that was the problem! Below and above I had material but not around. That's it!
