摘要：
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. © 2015 Sharif University of Technology.
