Problems solved by technology

Traditional metal antennas, including copper and gold, are easily oxidized by air and corroded in humid environments, which will lead to a decrease in antenna performance; at the same time, metal antennas are not easy to achieve good conformality. Leading to limited application of traditional antennas in the field of wearable technology

Abstract

The invention discloses a broadband omnidirectional wearable antenna based on graphite and a preparation method thereof. Based on high conductivity, bendability, physical and chemical stability and the like of graphite, the invention provides a graphite antenna working in an industrial scientific medical frequency band (ISM frequency band). The antenna has the advantages of being low in profile, wide in band, omnidirectional in radiation, capable of being attached to the surface of a human body and the like, a coplanar waveguide structure is adopted, the antenna is provided with a graphite radiation top layer structure and a braided fabric substrate structure, and SMA feed is adopted. The graphite radiation structure is formed by combining a plurality of equilateral triangles, and is simple in structure and easy to design and manufacture; the braided fabric substrate structure is made of common cloth and can be in direct contact with the skin of the human body. The antenna can be used for indoor positioning application, motion data monitoring and other scenes, and is an important part of intelligent wearable equipment in the future.

Description

technical field [0001] The invention relates to the technical field of antennas in the field of wearable communications, in particular to a graphite-based broadband omnidirectional wearable antenna and a preparation method thereof. Background technique [0002] Wearable communication technology is one of the rapidly developing technologies in recent years. Wearable technology is closely connected with the Internet of Things (IoT) technology, intelligent platform, and medical and health fields, and can be applied to sports monitoring, health management, and indoor positioning. As one of the key devices for sending and receiving signals in the communication system, the performance of the antenna is very important for the communication system. Especially in the field of wearable technology, in addition to good radiation conversion efficiency, the antenna should also have good conformal properties, compact size and wearing comfort. Traditional metal antennas, including copper a...
