Hi everybody,

I fabricated an antenna patch on the surface HIS, but now my antenne have two principal lopes , the gain is not so good, So anybody has the solution for me for augmenting the gain and for radiating only one lope's principal? pls help.
I will appreciate all the help.

Just a look ex..
 

We need some more information, what model were using to design and the substrate properties including its thickness. I have designed patch antennas and the patterns are quite okay.

if there are two principle lobes, that means it is higher mode not the doninant mode.
