Microstrip patch antenna used to send onboard parameters of article to the ground while under operating conditions. The aim of the paper is to design as tacked nearly square microstrip patch antenna design for S band 2 GHz to 4 GHz and study the effect of antenna dimensions Length (L), and substrate parameters relative Dielectric constant (εr), substrate thickness (h) on the radiation parameters of Bandwidth and Beam-width. A stacked patch configuration is proposed to increase the narrow bandwidth, radiation efficiency and directivity. The proposed antenna is probe fed on a FR-4 substrate with dielectric constant of 4.4. At resonant frequency 2.42 GHz, antenna parameters like Return Loss, VSWR, Axial Ratio and Radiation pattern are verify and simulated on CST Microwave Studio by CST student edition.
