Slotted antenna

Hi ! I am beginner in HFSS, please be cool ! ;)
I am trying to design a linear slotted antenna with rectangular waveguide.
I did the waveguide with the good dimenssions, then I added only one slot longitudinal. ( I did not want to put 15 slots, just one to try)
I put the dimenssion for that slot, a bit randomly ( this is always bad of course to do so). Then I did my radiation box above this slot.
My Problem is that when I get my radiation pattern , my total gain is really bad, like nothing ( - 80 dB around ).
My question is , does the problem comes from the dimenssions of my slot only ?
Thx !
