An Idea of Additional Modified Modes in Rectangular Patch Antennas Loaded With Metamaterial

In this letter, we have proposed a novel idea for producing additional modified mode(s) in a metamaterial-loaded rectangular patch antenna. The proposed idea has defined the possible range of variations of the material parameters for different kinds of metamaterials to get additional modified resonant mode(s). Moreover, we have also indicated the appropriate choice of particular metamaterial for different specific purposes like antenna size reduction and other mode modification-related applications. According to our proposed idea, it is possible to get better radiation performance for interface resonance mode by introducing modified TM 0δ0 modes ( 0
