摘要

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。

Optical nano patch antenna for terahertz applications with graphene

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.
