Abstract

The invention discloses a fabric metamaterial reflecting surface used closing to a human antenna. The fabric metamaterial reflecting surface used closing to the human antenna comprises a conductive fiber upper surface, a common fabric fiber material medium and a conductive fiber material floor; and the conductive fiber upper surface is composed of plurality rows and columns of concentric-square-shaped conductive fiber patches. Due to using fabric and conductive fiber materials, the fabric metamaterial reflecting surface used closing to a human antenna can be integrated into a position in the clothing where a wearable antenna is required. After using the fabric metamaterial reflecting surface disclosed in the invention, the radiation specific absorption rate of the wearable antenna to the human body is greatly reduced, and at the same time, the antenna gain is significantly improved in the direction away from the human body.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a metamaterial reflective surface. Background technique [0002] A wearable device is an electronic device that can be directly worn by a user. Such devices are often integrated into clothing, clothing accessories, or other wearable accessories. Currently more successful commercialized wearable devices include smart watches, smart bracelets and smart glasses. [0003] Common wearable devices basically have data collection and data transmission capabilities at the same time, and the capabilities of wearable devices are inseparable from the huge advantages brought by data interaction and even cloud processing and control. Therefore, wireless communication modules play a very important role in wearable devices. In addition to using conventional on-board antennas, some antennas specially designed for wearable device usage scenarios can improve the commun...
