Cosimulation and optimization of patch antenna using metamaterial

In terms of coverage area and high data transmission speed balance, the frequency band of 3.00-4.00 GHz will constitute the main frequency band of the 5G network. In this study, microstrip antennas with a less than -10 dB return loss are designed for the frequency band of 3.00-4.00 GHz. Antenna designs are provided with co-simulation between MATLAB and CST MW Studio software. The geometric dimensions of microstrip antennas have been optimized using genetic algorithm. As a result of the optimization process, wideband antennas with 3.5 GHz resonance frequency are obtained. Square split ring resonator is designed and geometric dimensions of it have been optimized using genetic algorithm. As a result of the optimization process, a metamaterial unit cell with negative permittivity and negative permeability is obtained between the 3.00-4.00 GHz frequency band. Metamaterial unit cell is combined as a 4x4 array form and antenna gain is increased by using metamaterial with microstrip antenna. Antennas optimized by genetic algorithm and microstrip antenna used with metamaterial are compared in terms of antenna parameters with some studies in the similar frequency range.
