L-Band Metamaterial Microstrip Antenna

High performance, compact size and low cost are the basic requirements of modern microwave communication systems. Various technologies have been developed to fulfill these requirements such as Substrate Integrated Waveguides (SIWs), Photonic Band Gap Structures(PBG), Defected Ground Structures (DGS), Electromagnetic Metamaterial structures and so on. Among these, Metamaterials are relatively new and the potential applications of these special classes of materials have drawn much attention in last few decades.
