Abstract :
Based on graphene, this paper proposes a configuration of a bandwidth broadened pattern-reconfigurable antenna. The antenna is a monopole surrounded by a cylindrical graphene-based impedance surface coating, and the radiation pattern is dynamically controlled via graphene´s field effect by applying adequate bias voltages. This antenna can work in the directional mode over the entire azimuth plane or omnidirectional mode; correspondingly, its relative bandwidth can reach 67% and 50% respectively by the coupling of graphene-based impedance surface coating.
