Reconfigurable Terahertz Patch Slot Antenna Based On Graphene with Metamaterial Structures
A graphene terahertz (THz) patch slot antenna is proposed and analyzed.The reconfigurable resonance of the graphene is investigated for efficient THz radiation.Thanks to graphene unique electric band structure, the two-dimensional (2D) graphene is modeled by the complex surface conductivity at THz.The proposed antenna is loaded with a reactive impedance surface (RIS), which significantly reduces the size of the antenna.It has the reconfigurable resonance from 1.56 THz to 1.6 THz with the applied external DC voltage and radiation efficiency over 75% around the central frequency of 1.562 THz.Parametric study on the antenna performance with the material properties have been carried out.The results reveal that the graphene-based antenna can find its applications for future graphene multi Terabit wireless data transmission and transparent all-graphene THz sensing systems.
