This paper presents novel compact and high performance microstrip patch antenna by using artificial dielectric. Cylindrical rods artificial dielectric is embedded in substrate of reference patch antenna, this makes the antenna compact, reflection coefficient improves and enhancement in impedance bandwidth is achieved. Technique of designing the cylindrical rods artificial dielectric in given frequency range is also presented in this paper. Practical swarm optimization technique (PSO) is used to design and optimize the proposed antenna. Finally, RMPA with cylindrical rods embedded substrate is proposed that provides 47.2% compactness, improved return loss and bandwidth. Mathematical analysis of proposed antenna is also done to verify the simulated results of proposed antenna. The effect of rods parameters (height, radius, and distance between rods) on the performance of patch antenna is also analysed.
