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.
