Abstract

Abstract In this paper, a wide bandwidth (20 GHz) and small sized (200 × 200 × 50 µm3) terahertz (THz) square graphene ribbon antenna using Photonic Band Gap (PBG) substrate are investigated in the 0.6–0.8 THz band. The proposed antenna consists of graphene as radiating patch mounted on four types of ground plane. The important aim of this work is to eliminate the second resonance frequency by utilize a several types of ground plane and keep a single frequency by improving the performance of the proposed antenna. The effect of change ground plane on the performance of antenna is compared, in terms of reflection coefficient, bandwidth, directivity and radiation pattern. The antenna has achieved good gain (7.62 dB) and good directivity (6.38 dB) in comparison to work reported in the literature.

接地平面对在高介电常数PBG结构衬底上设计的方形石墨烯带状贴片天线的影响

摘要本文在0.6–0.8太赫兹波段研究了一种使用光子带隙（PBG）衬底的宽带宽（20 GHz）和小尺寸（200×200×50µm3）太赫兹（THz）方形石墨烯带状天线。所提出的天线由石墨烯作为辐射贴片安装在四种类型的地平面上组成。这项工作的重要目的是通过利用几种类型的地平面来消除第二谐振频率，并通过提高所提出的天线的性能来保持单一频率。从反射系数、带宽、指向性和辐射方向图等方面比较了地平面变化对天线性能的影响。与文献中报道的工作相比，该天线获得了良好的增益（7.62dB）和良好的方向性（6.38dB）。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
