Abstract: Radiations improvement in a probe fed rectangular microstrip patch antenna using linear slot etched ground plane is proposed. Conventional MPA is designed using Glass Epoxy FR4 substrate. Substrate has dielectric constant 4.4 and its thickness 1.6 mm, operated at resonant frequency 3.05 GHz. The proposed method is simple and easy to etch on a substrate. This will suppress cross-polarized (XP) radiation field only without disturbing the dominant mode and co-polarized radiations. The concept has been tested using HFSS tool and verified its results experimentally. The experimental results show a good agreement with the simulation results.
