Abstract This paper proposes an enhancement radiation efficiency method of graphene-based patch antenna using partially strip slot ground plane removal. Graphene as a one-atom thickness (2D) supports surface plasmon polariton (SPP) of considerably decreasing wave length in comparing to the free space one. Based on this fact yields efficiency of graphene antennas is degraded. The effect of strip line ground plane removal reduces the losses due to dielectric substrate and surface waves. The proposed design has reached up to 90% at both radiation and total efficiency. Also due to using graphene, it can provide tunable conductivity derived from variable parameters. The graphene-based patch THz antenna is modeled to achieve the optimum parameter values.
