▎ 摘　　要

NOVELTY - The antenna comprises excitation antenna and antenna radiation module formed by arranging lattice unit. Each of the lattice unit comprises grounding dielectric substrate, graphene patch and electrostatic bias plate. The graphene patch is located on grounding dielectric substrate. The electrostatic bias plate is located below the graphene patch to change the conductivity of corresponding graphene patch USE - Terahertz graphene holographic impedance surface antenna for use in terahertz frequency band communication system. ADVANTAGE - The terahertz graphene holographic impedance surface antenna uses single-layer square high-impedance graphene as impedance patch unit, patch and equal size are arranged, simple structure shape rule is easy to manufacture, graphene patch relative to the metal patch, is more inductive, impedance is with surface impedance modulation range. It has good radiation performance in the passband, loading different bias voltage on different graphene patches, drawing the hologram impedance map. When illuminated by the source wave, the impedance surface as the target wave, by adjusting the bias voltage loaded on each graphene patch to form different impedance map, the antenna can realize the beam scanning of the target beam in the two-dimensional direction without changing the antenna structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of terahertz graphene holographic impedance surface antenna.
