Abstract
Plasmonic mode propagation properties of a graphene strip placed on a
substrate are studied in the THz range. Based on propagation properties (phase constant),
a design guide for a dipole-like antenna made of graphene strips is presented. The input
impedance and the radiation properties of such graphene-based antenna are investigated
through full-wave numerical simulations. Full-wave simulations show that graphene
antennas can provide higher input impedance, along with the tunability of the resonance
frequency, which are two important design requirements in high performance terahertz
photoconductive antenna sources and detectors.
