摘要

近年来，石墨烯以其优异的性能引起了人们的广泛关注。许多基于石墨烯的新型器件已经问世，显示出石墨烯在太赫兹波段应用的巨大潜力。在本文中，通过在SiO2/Si衬底上放置单层石墨烯，利用石墨烯的电压可控导电性获得了可调谐的石墨烯偶极子天线。该天线的共振频率随化学势的增加呈蓝移。此外，通过调整化学势，天线的辐射增益可以从3.7dBi增加到5.5dBi。这些模拟结果将提供在可重构天线中使用石墨烯的方法。

A tunable THz dipole antenna based on graphene

Recently graphene has attracted tremendous attention for its excellent properties. Numerous novel graphene-based devices have come out, showing great potential of graphene for applications at the terahertz band. In this paper, by placing monolayer graphene deposited on top of a SiO2/Si substrate, a tunable graphene-based dipole antenna owing to the voltage-controllable conductivity of graphene is obtained. The resonance frequency of the proposed antenna is blue-shift with increasing chemical potential. Furthermore, the radiation gain of the antenna can increase from 3.7dBi to 5.5dBi by adjusting the chemical potential. These simulated results will provide approaches using graphene in reconfigurable antennas.
