Scattering of the terahertz radiation on a graphene-based nano-antenna is considered. Different electromagnetic models of graphene are discussed and applied to calculate extinction, scattering and absorption cross sections of the nano-antenna. Scattering resonances in the terahertz band are identified as longitudinal Fabry-Perot resonances of surface plasmon polaritons supported by the graphene layer. A simple while powerful model, based on the effective mode index of plasmon polaritons, is proposed to predict the antenna resonant properties. A systematic numerical study of the graphene-based nano-antenna is presented for different antenna dimensions. Finally, the potential of graphene-based nano-antennas for terahertz applications is discussed.
