Design and Characterization of Coaxial Feed Circular Patch Antenna on a Metamaterial Substrate

This paper discusses a band width improvement of circular patch antenna (CPA) realized by using electromagnetic metamaterial and operating at 12GHz resonance frequency. Electromagnetic Metamaterial is a artificial material which is made up of different structures on dielectric substrates. This structure is called unit cell of metamaterial. Periodic arrangement of this unit cell forms Metamaterial. Material consist of an atoms in the same way metamaterials are having small metallic resonators of different shapes depending on resonance frequency. This is having effect on external Electromagnetic waves. Circular patch antenna substrate is loaded with CSRR. Conventional patch antenna and proposed patch antenna are simulated using FEKO software. The bandwidth of both antennas are compared.
