石墨烯由于其独特的电学、机械和光学特性，在广泛的领域得到了广泛的应用。其中，基于石墨烯的等离子体小型化天线（或简称为石墨烯天线）在通信领域引起了越来越多的兴趣。由于石墨烯的尺寸减小，在微米范围内，预期的辐射频率为几太赫兹，因此石墨烯为实现超短距离无线通信提供了手段。由于石墨烯的高辐射频率和潜在的宽带特性，本文提出了一种石墨烯的时域表征和评价方法。提议的框架是高度垂直的，因为它旨在建立技术方面、天线设计和通信之间的桥梁。利用这种方法，定性和定量分析了石墨烯的两个关键设计参数的函数，即化学势和载流子迁移率。然后将结果与等效金属天线的性能进行比较。最后，简要讨论了石墨烯在超短程通信中的适用性。
Graphene is enabling a plethora of applications in a wide range of fields due to its unique electrical, mechanical, and optical properties. Among them, graphene-based plasmonic miniaturized antennas (or shortly named, graphennas) are garnering growing interest in the field of communications. In light of their reduced size, in the micrometric range, and an expected radiation frequency of a few terahertz, graphennas offer means for the implementation of ultra-short-range wireless communications. Motivated by their high radiation frequency and potentially wideband nature, this paper presents a methodology for the time-domain characterization and evaluation of graphennas. The proposed framework is highly vertical, as it aims to build a bridge between technological aspects, antenna design, and communications. Using this approach, qualitative and quantitative analyses of a particular case of graphenna are carried out as a function of two critical design parameters, namely, chemical potential and carrier mobility. The results are then compared to the performance of equivalent metallic antennas. Finally, the suitability of graphennas for ultra-short-range communications is briefly discussed.
