Plasmonic patch antenna based on graphene with tunable terahertz band communications

This paper proposes a plasmonic graphene-based patch antenna for THz application in detailed analysis. Here, a rectangular patch antenna based on graphene presenting the Surface Plasmon Polariton (SPP) waves behavioral in graphene sheet is proposed and analyzed. In addition, the characteristics of graphene are presented and analyzed. In the Ffollowing, the SPP wave propagation in graphene is numerically and analytically studied. The numerical simulations with COMSOL and CST, Computer Simulation Technology transient solver, are presented in proposed structure. These solvers demonstrate that the efficiency of a rectangular graphene patch drastically improved by increasing the graphene layers. In order to achieve the desired low tunable terahertz band communication, parametric study method is applied on the proposed antenna.
