THz Pattern Reconfigurable Antenna using Graphene-based Frequency Selective Surface

This thesis presents a THz pattern-reconfigurable antenna using graphene-based frequency selective surface (GFSS).The center of the antenna is an omnidirectional monopole antenna surrounded by graphene-based frequency selective surface (GFSS) which arranged in a square shape. The radiation pattern of the antenna can be reconfigured by dynamically commanding the chemical potential of graphene. The antenna can operate in directional mode over the entire azimuthal plane or omnidirectional mode. In addition, it also can adjust the gain continuously.
