A high gain omnidirectional antenna using metamaterial rods

Abstract

A metamaterial rod as a superstrate consisting of a periodically cylindrical rod is proposed for gain enhancement of omnidirectional microstrip patch antenna. The metamaterial rod exhibits near zero permeability that it reflects partially wave. This designed technique could be confirmed by a measurement result from prototype antenna that agrees with simulation results. The results indicate that the metamaterial rod can also enhance the radiation characteristics and efficiency, the proposed antenna generates an omnidirectional pattern in the azimuthal plane with the maximum gain of 19.47 dBi. The frequency of a high gain omnidirectional antenna using metamaterial rods is designed at 920 MHz for prepaid mobile application.
