hi all
i modelled the antenna in hfss and run it, but somehow the result is not what i expected, with a S11 around -2db, something must be wrong
the antenna is already published and i modelled exactly according to the dimension. it's a UWB antenna with bw 3.1g to 10g
i went thru the design for several times however the result is the same
could some one tell me what's wrong with my design?? i doubt it's due to the port coz i assigned a lumped port instead of wave port which i think is much easier.
might be due to solution frequency, setup , etc . juz not sure
i attached the zipped file

i found out whats wrong with it
it has nothing to do with the setup, the patch in the ground side should be in the other direction.
