Abstract
Microstrip Patch Antenna is a narrowband antenna fabricated by etching the antenna element pattern in metal trace of elements like copper bonded to an insulating dielectric substrate with a continuous metal layer on the opposite side of the substrate which forms a ground plane. Electromagnetic Metamaterial is an artificial material that is made up of different types of structural designs on dielectric substrates. In this paper, a broad and elite investigation is being carried out by designing and simulating a single negative metamaterial cell comprising a square split ring resonator. This metamaterial cell depicts negative values of permeability for a specific range of frequencies. These cells show exceptionally great applications in the design of microstrip patch antenna. The substrate of the microstrip patch antenna with a ground plane is loaded with a square split-ring resonator, Conventional and proposed patch antennas are simulated, analyzed, and reported for performance comparison of its parameters. The proposed edge port feed metamaterial based Rectangular microstrip patch antenna and Circular patch antenna designed at 26 GHz resonance frequency useful for 5G applications. Both antennas are designed on RT Duroid 5880 Substrate with 2.2, dielectric constants. The parameters such as bandwidth, gain and return loss of metamaterial loaded rectangular microstrip patch antenna and Circular patch antenna increases considerably compared to conventional antennas. Comparing parameters of both antennas, the performance of the rectangular microstrip patch antenna is found to be better than circular patch antenna.

Summary
Microstrip patch antennas are being widely used for small wireless communication aerospace applications WiMAX, WLAN, and 5G applications. Bandwidth can be increased by loading metamaterial on a microstrip patch antenna. The metamaterial-based Rectangular microstrip patch antenna (RMPA) is simulated and bandwidth, return loss, and gain are measured. Mu (single) negative metamaterial cells are loaded on the ground plane of the rectangular and circular patch antenna. A significant improvement in patch antenna parameters has been observed [3] [4] [5] [6] They are artificial materials that show negative permittivity permeability and refractive index. The magnetic field vector of the incident plane wave is perpendicular to the SSRR, which gives rise to the induced currents resulting in an effective magnetic moment that eventually will yield the negative permeability. The inherent feature of CST is used to invoke the CST platform through MATLAB script file [9] [10]
