High-Gain Multi-Layer Antenna Using Metasurface for Application in Terahertz Communication Systems

Abstract

In this paper, a novel high-gain multi-layer antenna is designed for use in terahertz communication systems. The frequency range covered by this antenna is 8-13 THz. To improve the antenna’s gain, a proposed rectangular metasurface structure environment has been used. To strengthen and connect the layers, several plastic bases have been used, which do not have a destructive effect on the antenna’s radiation pattern. The use of the proposed rectangular metasurface structure medium has increased the gain by more than 10.5 dB compared to the conventional antenna. The maximum gain is 14.7 dB at 12 THz. The final dimensions of this antenna are 24 × 28 × 21.6 mm 3 at 12 THz.
