In this article, the design of metamaterial (MTM) microstrip patch antennas (MPA) for multiband and wide band applications is investigated, and the MTM unit cell S-shape loaded reactive impedance surface (S-RIS) is analyzed for square and triangular shape patch antennas.Abstract:
This paper investigates the design of metamaterial (MTM) microstrip patch antennas (MPA) for multiband and wide band applications. The MTM unit cell S-shape loaded reactive impedance surface (S-RIS) is analyzed for square and triangular shape patch antennas. The array of S-RIS unit cell formed metasurface for microstrip patch antenna. It is observed that triangular shape patch gives high bandwidth of 2GHz with directive gain of 5.53dBi while a square shape provide resonance at two frequencies.read more
