ground plane dipole directivity
Hi,everyone
I am using HFSS to simulate dipole antenna near metal ground plane. the dipole is parallel to the metal ground plane.
when i simulate this dipole antenna for 2.4Ghz centre frequence and place it very close to ground plane 1mm to be exact i get badly matched dipole shown by s parameter.
however when i check the farfield pattern at 2.4 ghz,the gain is around 9dbi and its giving smooth and wide main lobe with maximum in Theta=0 degree.
can anyone explain this why this is happening because in my view if antenna's s parameter is not good it should not radiate and its gain should be very low.
any help would be highly appreciated.
thanks
