Abstract –In this paper , a new matametrial structure (MTM) implemented in microstrip transmission line configuration is proposed and its parameters like return loss, gain and bandwidth are analyzed. Hence a metamaterial structure of “wired and Interconnected Rings” is designed such that it exhibits negative permittivity and negative permeability at the same frequency as that of inset fed rectangular microstrip patch antenna. Here NRW parameters are used to verify negative permittivity and negative permeability. This structure is then superimposed on the microstrip patch antenna and its parameters are again analyzed. Then a varactor diode as active device is added to the metamaterial structure and again parameters are analyzed using CST microwave studio software Further improvement in antenna parameters are observed.References
