The smith chart is very helpful for power transmission analysis.ДЄmong the antenna applications of microwave and radio frequency substrate materials, the metamaterial is most relevant. Smith chart can be used to convert reflection coefficient to normalized impedance. Figure 7 and 8 shows the smith chart of S parameter S1,1 and S2,2. Smith chart plot represents antenna impedance variation with frequency. This is power transmission graph plot from port 1 to port 2 (S1,2).ДЇigure 6 shows the impedance bandwidth of 53MHz, which is calculated asДЇig. Thus the return loss of proposed square antenna is -19.74 dB at 10.204 GHz frequency as shown in figure 5. Simulation result with return loss and bandwidth of square antenna is shown in figure 5 and 6.

Dimensions of square metamaterial structureДesign of unit of metamaterial antenna proposed is shown above with dimensions. The parameters of square microstrip patch antenna are calculated from following formulas mention below: Thus two waveguide ports are along x axis. There is a perfect magnetic axis towards z axis, y axis is perfect electric axis and x axis is open. In this paper, the unit cell of metamaterial antenna has two square rings as shown in figure 1. Boundaries view of metamaterial structure Dielectric substrate with low dielectric constant gives better radiation, wide bandwidth and good efficiency.ДЇig. Generally conducting material like copper or gold is used for patch. The performance of microstrip antenna depends on dimensions of antenna, substrate material, feeding technique. The square geometry is smaller in size for a given frequency as compared to circular geometry. The proposed square microstrip patch antenna has wide impedance bandwidth. But metamaterial based microstrip patch antenna gives significant improvement in bandwidth and return loss. The disadvantage of antenna is that the bandwidth is limited to few percent. The impedance bandwidth and return loss are important parameters of antenna.

The electric field is zero at the centre of patch. There is a narrow gap between the patch and the ground plane. Patch antenna requires low profile thus patch antenna consists of thin conducting sheet of about 1 by 1/2 mounted on surfaces. Now a days, wireless communication system commonly use microstrip patch antenna for wireless devices as microstrip patch antenna has low weight, low cost, designДЄnd technology. 1.Front view of unit cell metamaterial antenna structure CST Microwave Studio is used to design, simulation, and analyze the antenna.ДЇig. The performance of our fabricated antenna was analyzed and measured. In our project microstrip patch antenna is designed with frequency range 1 to 3GHz. Thus metamaterial is used to improve the low gain and efficiency in wireless communication. At the present day, substrates with low dielectric constant are preferred for getting maximum radiation. Metamaterials have a property that is not found naturally, it consists of artificial metallic structure which have negative permeability (Г‚Вµ) and permittivity ().
