Abstract
In this paper we present a numerical analysis of graphene nanoantennas with rectangular, elliptical, triangular and circular geometries in terahertz band. We model the electromagnetic scattering of these planar structures by the method of moments with the surface impedance of graphene. We analyze the absorbing cross section and the resonances of nanoantennas for different, sizes, chemical potential, temperature and incident angle. The obtained results can be useful to design efficient nanoantennas for terahertz wireless communications.
