用于人体中心网络的超宽带可穿戴织物天线

一种用于人体中心网络的超宽带可穿戴织物天线

内容简介：人体中心网络是第四代移动通信（4G）的一个重要组成部分，可应用在一些特定的场合，如火灾现场、战场和老年人监护等。天线是人体中心网络研究中的核心问题。人体中心网络天线研究中最重要的研究方向是可穿戴式织物天线，因为它易集成到衣物中，既方便携带，又不易被察觉。由于超宽带具有低功耗、低成本、低截获率等优点，因此一直是无线通信研究的热点。本文设计了一种用于人体中心网络的超宽带可穿戴织物天线。该天线采用共面单极子结构，在不靠近人体时带宽为3.2GHz-10.6GHz。将天线靠近人体时，采用含皮肤、脂肪、肌肉的三层人体模型进行仿真，结果S11及方向图指标均有一定程度的下降，但仍能满足人体中心网络应用需求。

Abstract：In recent years, body-centric wireless communication becomes an important part offourth generation mobile communication systems ( 4G). It could beused in some specialized occupations, such as fire fighters, military and monitoring the aged. Antenna is a most important issue in this area. One of the dominant research topics in antennas for body-centric communications is wearable, textile-based antennas because it could be easily worn on body and integrated in to clothes. Ultra-Wideb and (UWB) is good for low power, low cost and is hard to detected, so it is a hot topic in the wireless communication research . This paper designed a UWB wearable tex tile an tenna for body-centric wireless communications. The proposed antenna was a planar monopole antenna with the bandwidth 3.2G Hz-10.6GHz when off the body. When it was near the body, we sim ulated the human body as three-layer model including skin, fat and muscle and found there was a decrease in S11 and radiation pattern, however, it could also meet with the body-centric wireless communications needs.
