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.

Aiming at wearable electronic equipment in wireless body area network communication, we propose a circularly polarized wearable antenna based on artificial magnetic conductor (AMC) for the problem of unreliable data transmission of linearly polarized wearable antenna and reduction of transmission distance due to the low gain of antenna. The AMC of in-phase reflection reflects the backward radiation to the top to reduce the damage of the antenna to human body. And the polarization direction of the reflected wave reflected through AMC is the same as that of the main direction, which makes the radiation performance of the antenna improved. Meanwhile, the antenna is flexible and lightweight due to the use of flexible polyimide and graphene films as the substrate and conductor materials. The antenna was also simulated and the prototype was fabricated and tested. The simulation results show that the working bandwidth covers 2.4–2.48 GHz, and the peak gain is 8.09 dBi. The peak specific absorption rate of 1 g and 10 g of human tissue at an input power of 350 mW is 1.48 W kg−1 and 0.65 W kg−1, respectively, which meets the safety standards.
