Aim: This study aims to design a rectangular microstrip patch antenna with Novel S and 2 shaped slots at 2.45 GHz and to compare its gain performance with an S-shaped rectangular Microstrip patch antenna. Materials and Methods: Two groups, S-shaped microstrip patch antenna and Novel S and 2 shaped microstrip patch antenna are simulated with 10 samples each. Each group is simulated for 8 iterations. Microstrip patch antenna patch length, width, height, the dielectric constant of the substrate, and resonance frequency are used for gain performance analysis. The alpha error-threshold of 0.05 was kept with a 95% confidence interval and 80% pre-test power
