Abstract :
This paper investigates the effect of a metamaterial superstrate on a single-feed circularly polarized microstrip patch antenna (SFCP-MPA) using CAD simulations. Simultaneous enhancement on antenna gain (up to 3dB), impedance bandwidth (BWZ) and axial ratio bandwidth (BWAR) are observed as well as multi-frequency operations at 5.125 GHz, 11.34 GHz 12.43GHz. Also it is observed that the invisible first harmonic becomes prominent and visible. Besides, the result also suggest that the Superstrate acts as a DRA (at 12.43GHz).
