problem with SIW antenna in HFSS

Hi.
I am working on SIW horn antenna design using HFSS.
I found one such thing in an article and put all the dimensions but I don't get the results in the article.(results are not even reasonable)
I was wondering if sbody will take a look at the design attached and help me if I made sthing wrong.
S11 pattern is odd(the minimum far far from the designed freq 27GHz)
E_Plane Gain pattern maximum @ 30 degree instead of 0.

why doesn't anyone answer?
this is a picture of the antenna
hi your design had not ground plane
to contact me: ferdows_j@yahoo.com
He has defined the bottom face of the structure as PEC, so it does not need a ground plane
The size of waveport seems to be needlessly very large.
The transition from SIW to microstrip seems to be incorrect.
I think the problem of this design is that there is no integration line defined for the wave port!
