Abstract

The invention discloses a transparent nanomaterial antenna capable of realizing capacitive coupled feed. The antenna is made of a transparent carbon nanomaterial and realizes non-contact feed with a capacitive coupling method, and antenna impedance matching is realized through design and optimization of sizes and shapes of capacitive electrodes, the distance between the electrodes, a dielectric material and the dielectric constant. The antenna comprises a graphene antenna, a carbon nanotube antenna or a graphene and carbon nanotube combined antenna, and the antenna is a nanoscale antenna made of one or more layers of graphene or carbon nanotube materials. The transparent nanomaterial antenna solves problems that the carbon nanomaterial is incompatible with metal interfaces of traditional feed structures, high in contact resistance, difficult in impedance matching and the like. The transparent nanomaterial antenna is excellent in performance, thin, transparent, bendable, foldable, printable, bondable, capable of being embedded in a smart phone, smart glasses, a wearable electronic device and the like, attractive in appearance and practical and has a communication function.

Description

technical field [0001] The invention relates to the design of transparent nanomaterials such as graphene or carbon nanotube antennas, in particular to a capacitive coupling feeding design and impedance matching method. Background technique [0002] Graphene is a single atomic layer metamaterial with many excellent electrical, thermal, mechanical and other material properties and broad industrial application prospects, especially in the fields of electronics, communications and smart devices. For example, the literature, K.S.Novoselov et al., Nature, Vol490, 2012, pp.192, discusses the excellent properties and development roadmap of graphene materials. Graphene is currently known as the material with the best electrical conductivity, and antennas made of graphene materials can work at terahertz (THz) frequencies. On the other hand, carbon nanotubes have excellent electromagnetic wave propagation properties. Recently, breakthroughs have been made in the preparation of macros...
