Zolfagharloo Koohi Department of Electrical Engineering and Computer Science, University of Michigan, Ann Arbor, MI, 48109. M. Neshat School of Electrical and Computer Engineering, University of Tehran, Tehran, Iran Journal Article 2015 05 05 Plasmonic mode propagation properties of a graphene strip placed on a substrate is studied in 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 that are two important design requirements in high performance terahertz photoconductive antenna sources and detectors. https://scientiairanica.sharif.edu/article_3720_fe2184ec1aacf8d0cd56a2d6e567a964.pdf
