— This paper presents the effects of superstrate & designed to enhance the performance parameters of rectangular microstrip patch antennas. The modified split ring resonator (MSRR) is used in design. At frequency 2.2 GHz, the microstrip patch antenna is designed with the help of superstrate. Metamaterial superstrate is a significant method to obtain high directivity of one or a few antennas. In this paper, the characteristics of directivity enhancement using metamaterial structures as antenna superstrates that is artificial magnetic superstrate. This design helps to enhance gain and efficiency of microstrip patch antenna at resonance frequency. The simulated and observative results through HFSS, 10 db impedance bandwidth of rectangular microstrip patch antenna is at 2.2 GHz, The radiation efficiency, gain and directivity of proposed antenna are presented at 2.2 GHz. The coding has been done by MATLAB and simulation results has been done by HFSS.

The addition of a dielectric layer on a slab configuration is frequently utilized in various electromagnetic devices in order to give them certain desired operational characteristics. In this work, we consider a grounded dielectric film-slab, which is externally excited by a normally-incident Gaussian beam. On top of the film-slab, we use an additional suitably selected single isotropic superstrate layer in order to increase the field concentration inside the slab and hence achieve optimal power transfer from the external source to the internal region. We define a quantity of interest, called "enhancement factor," expressing the increase of the field concentration in the film-slab when the superstrate is present compared to the case that it is absent. It is shown that large enhancement factor values may be achieved by choosing properly the permittivity, the permeability, and the thickness of the superstrate. In particular, it is demonstrated that the field in the film-slab is significantly enhanced when the slab is composed by an -near-zero (ENZ) or low-index metamaterial.
