After the invention of Carbon Nanotubes (CNTs) by Iijima and Bethune et al. in 1991, numerous fields have opted CNTs for the design and fabrication of compact, miniature, and light weight components and devices. The electronics and communication device like transistors, interconnects for printed circuit boards (PCB) and integrated chips (ICs), filters, and amplifiers have seen a huge transition in terms of materials selection and miniaturization with the adoption of CNTs as the replacement for the metallic parts. The research articles available in open literature give a strong influence of CNTs in the field of Antennas and Propagation. The CNTs have drawn the attention of antenna engineers due to their light weight, low cost, corrosion resistance, temperature stability, tunable conductivity, extraordinary flexibility and elasticity, lower thermal expansion coefficient, and higher tensile strength. Both Single Walled CNTs (SWNTs) and Multi Walled CNTs (MWCNTs) are utilized for the construction of antennas. Basically the conductivity of SWCNTs and MWCNTs is not adequate to achieve desired radiation efficiency. So, techniques such as bundling/ threading of CNTs and doping are adopted to enhance the conductivity of CNTs and radiation efficiency of antennas. In this article a review of CNT based Antennas is made with respect to the types of CNTs being used. This article is also aimed to cover the merits and demerits of CNTs being used in different antennas. This survey also covers recent advancements in CNT materials and fabrication techniques pertaining to the antenna realization.

碳纳米管在天线实现中的应用进展

Iijima和Bethune等人发明了碳纳米管(CNTs)之后。1991年,众多领域选择CNT来设计和制造紧凑,微型和轻量级的组件和设备。电子技术和通信设备,例如晶体管,印刷电路板(PCB)和集成芯片(IC)的互连,滤波器和放大器,在材料选择和小型化方面发生了巨大的转变,采用碳纳米管(CNT)替代了金属部分。公开文献中的研究文章对碳纳米管在天线和传播领域的影响很大。碳纳米管因其重量轻,成本低,耐腐蚀,温度稳定,可调节的电导率,非凡的柔韧性和弹性而受到天线工程师的关注,较低的热膨胀系数和较高的拉伸强度。单壁CNT(SWNT)和多壁CNT(MWCNT)均用于天线的构造。基本上,SWCNT和MWCNT的电导率不足以实现所需的辐射效率。因此,采用诸如碳纳米管的束缚/穿线和掺杂的技术来增强碳纳米管的导电性和天线的辐射效率。在本文中,针对所使用的CNT的类型对基于CNT的天线进行了回顾。本文还旨在介绍用于不同天线的CNT的优缺点。该调查还涵盖了与天线实现有关的CNT材料和制造技术的最新进展。单壁CNT(SWNT)和多壁CNT(MWCNT)均用于天线的构造。基本上,SWCNT和MWCNT的电导率不足以实现所需的辐射效率。因此,采用诸如碳纳米管的束缚/穿线和掺杂的技术来增强碳纳米管的导电性和天线的辐射效率。在本文中,针对所使用的CNT的类型对基于CNT的天线进行了回顾。本文还旨在介绍用于不同天线的CNT的优缺点。该调查还涵盖了与天线实现有关的CNT材料和制造技术的最新进展。单壁CNT(SWNT)和多壁CNT(MWCNT)均用于天线的构造。基本上,SWCNT和MWCNT的电导率不足以实现所需的辐射效率。因此,采用诸如碳纳米管的束缚/穿线和掺杂的技术来增强碳纳米管的导电性和天线的辐射效率。在本文中,针对所使用的CNT的类型对基于CNT的天线进行了回顾。本文还旨在介绍用于不同天线的CNT的优缺点。该调查还涵盖了与天线实现有关的CNT材料和制造技术的最新进展。因此,采用诸如碳纳米管的束缚/穿线和掺杂的技术来增强碳纳米管的导电性和天线的辐射效率。在本文中,针对所使用的CNT的类型对基于CNT的天线进行了回顾。本文还旨在介绍用于不同天线的CNT的优缺点。该调查还涵盖了与天线实现有关的CNT材料和制造技术的最新进展。因此,采用诸如碳纳米管的束缚/穿线和掺杂的技术来增强碳纳米管的导电性和天线的辐射效率。在本文中,针对所使用的CNT的类型对基于CNT的天线进行了回顾。本文还旨在介绍用于不同天线的CNT的优缺点。该调查还涵盖了与天线实现有关的CNT材料和制造技术的最新进展。
