Hi,

so first of all, take care of the RadiationBox dimensions...from the HFSS guide we know that this should be at least at lambda/4 from the radiating surfaces..check you design to assure that.


What is the frequency range ?

Try feeding with lumped port and reduce its size. Make it equal to the feed (in width ) and length = substrate thickness, I guess it is touching the gnd.
