摘要：
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.
