Abstract

Nano optical crescent patch antenna for Terahertz applications using Graphene is designed in this paper. The antenna is designed at 7.28 THZ with several substrates material as PTFE (²r = 2.1), polymide (²r = 3.5), RO3003 (²r = 3), RO4003 (²r = 3.4) and Arlon AD (²r = 2.5). Graphene is the material patch used with different properties such as chemical potential µc = 0.2 eV, relaxation time τ = 1 ps and thickness of 60 nm to achieve a high gain and bandwidth. We obtained a very good performance of crescent antenna at 7.28 THZ with −37.962 dB, 7.124 dBi, 1.767 THZ of return loss, gain and bandwidth respectively which is very satisfactory for terahertz transmission between [0.1-10] THZ.

太赫兹石墨烯光学纳米贴片天线

设计了一种用于太赫兹应用的石墨烯纳米光学新月形贴片天线。该天线设计在7.28 THZ，衬底材料为PTFE(²r = 2.1)，聚酰胺(²r = 3.5)， RO3003(²r = 3)， RO4003(²r = 3.4)和Arlon AD(²r = 2.5)。石墨烯是利用化学势µc = 0.2 eV、弛豫时间τ = 1 ps、厚度为60 nm等不同特性来实现高增益和带宽的材料贴片。在7.28 THZ下，月牙形天线的回波损耗、增益和带宽分别为- 37.962 dB、7.124 dBi和1.767 THZ，在[0.1-10]THZ之间的太赫兹传输中非常满意。
