New Advances in Antenna Design toward Wearable Devices Based on Nanomaterials

Abstract

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.

“…In the 5G era, the operating frequency is in the millimeter wave band. Because waves are generally short, antennas are mainly targeted at applications such as short-distance communications, 5G communications, wireless communications [1][2][3] and imaging radar [2,4,5]. Antennas are widely used in various communication systems, closely integrating people and things throughout the world, forming an interconnected world [4,6].…”
