Boundaries view of metamaterial structure Dielectric substrate with low dielectric constant gives better radiation, wide bandwidth and good efficiency.įig. 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, designĪnd technology. 1.Front view of unit cell metamaterial antenna structure CST Microwave Studio is used to design, simulation, and analyze the antenna.įig. ![]() 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 (µ) and permittivity (). KeywordsSquare microstrip antenna, Metamaterial structure, Bandwidth, Return loss. We use CST microwave studio for designing the square microstrip patch antenna using metamaterial structure. This provide better bandwidth of 53 MHz with return loss -19.74 dB at 10.204 GHz frequency. It is designed with two port square microstrip antenna for operating 1-3 GHz frequency range. ![]() Women Engineering College Ajmer Ajmer, IndiaĪbstractIn this paper, we design a square microstrip patch antenna using metamaterial.
