I cannot figure out what is wrong with my design on FEKO, files are attached

I am trying to recreate the antenna in the pdf file but i am not getting the same results as the authors. The gain and the VSWR do not match, however, the gain increases when i remove the ground of the antenna and change the dielectric to default. any idea on why that happens? I experienced the same problem with the design of another patch antenna. Thanks

Hi Chinaza,

the design in the paper seems to be mirror-symmetric, but your design is not. Maybe this is the reason for the different results?!
