“…In this context, the idea of making dipole antennas work with high frequency and high efficiency by coating SWCNT came up [65]. Hajjyahya et al [66] compared the efficiency versus frequency of SWCNT-coated and uncoated dipole antennas of different lengths and constant radii and showed that the coating enables the efficiency of the antenna to be about 59% with zero loss and about 77% with impedance mismatch. This higher efficiency value and faster data rate will be very effective for biomedical engineering.…”

Wearable antennas have recently garnered significant attention due to their attractive properties and potential for creating lightweight, compact, low-cost, and multifunctional wireless communication systems. With the breakthrough progress in nanomaterial research, the use of lightweight materials has paved the way for the widespread application of wearable antennas. Compared with traditional metallic materials like copper, aluminum, and nickel, nanoscale entities including zero-dimensional (0-D) nanoparticles, one-dimensional (1-D) nanofibers or nanotubes, and two-dimensional (2-D) nanosheets exhibit superior physical, electrochemical, and performance characteristics. These properties significantly enhance the potential for constructing durable electronic composites. Furthermore, the antenna exhibits compact size and high deformation stability, accompanied by greater portability and wear resistance, owing to the high surface-to-volume ratio and flexibility of nanomaterials. This paper systematically discusses the latest advancements in wearable antennas based on 0-D, 1-D, and 2-D nanomaterials, providing a comprehensive overview of their development and future prospects in the field.

“…Указанные структуры могут иметь высокий поверхностный импеданс [38,39], а из-за их относительно малых длин они интересны в THz-и ИК диапазонах [28][29][30][31][32][33][34][35][36][37]. Перспективно исследование взаимодействия как отдельных УНТ [40][41][42][43], так и их массивов с электромагнитным полем, причем взаимодействие может быть как резонансным, так и нерезонансным при этом важны пондеромоторные силы [44]. Возбуждение таких антенн точечными (локализованными) источниками затруднено, но наноантенны из УНТ и графеновых нанолент можно сделать активными, например, путем оптической накачки [32][33][34]36,37,45].…”

Methods of inversion of integro-differential operators of thin linear antennas and also related to the dispersion interaction of the Casimir-Lifshitz force between two thin linear objects described by the dielectric constant in the form of Drude-Lorentz are considered. A new rigorous model for calculating Casimir-Lifshitz forces for thin dielectric or conductive filaments based on the Lorentz force is proposed. To determine correlations, the formulas of G.T. Markov, the fluctuation-dissipation theorem and the principle of detailed equilibrium with a thermal field were used. Analytical estimates of the obtained spectral integrals are performed in the far zone.

The SWCNTs-dipole antenna is one of the most potential CNTs antennas in the nanotechnology antenna field, especially for the infrared (IR) and terahertz (THz) frequency ranges [2,[10][11][12][13][14]. For the purpose of comparison the SWCNT dipole antenna with metal dipole antenna results, it is benefit to implement a comparison of these antennas with same size and shape [2].…”

This paper presents two different materials-based carbon nanotube composite (CNT-composite) material for antenna applications. These materials are single-walled CNT SWCNT and single-walled CNT composite material SWCNT-composite. The SWCNT are coated by a thin layer of (graphite, silver, or copper) material to construct new Nano-materials. Scientific and mathematical modeling approaches are presented in order to estimate the electromagnetic properties of these materials into CST (MWS) software package. For the purpose of supporting these modeling approaches, the required mathematical analysis is presented and discussed. The dipole antenna configuration will be utilized to estimate the electromagnetic properties of the SWCNT-composite a material. The results of this work showed the enhancement in the electromagnetic properties of the SWCNT-composite materials compared with the SWCNT material, respectively. The bandwidth and fractional bandwidth are the main enhance parameters that will be focused in this work.
