Abstract

In this paper, the utilization of common fabrics for the manufacturing of e-textile metamaterial transmission lines is investigated. In order to filter and control the signal propagation in the ultra-high frequency (UHF) range along the e-textile, a conventional metamaterial transmission line was compared with embroidered metamaterial particles. The proposed design was based on a transmission line loaded with one or several split-ring resonators (SRR) on a felt substrate. To explore the relations between physical parameters and filter performance characteristics, theoretical models based on transmission matrices' description of the filter constituent components were proposed. Excellent agreement between theoretical prediction, electromagnetic simulations, and measurement were found. Experimental results showed stop-band levels higher than -30 dB for compact embroidered metamaterial e-textiles. The validated results confirmed embroidery as a useful technique to obtain customized electromagnetic properties, such as filtering, on wearable applications.

摘要

本文研究了利用普通织物制造电子纺织超材料传输线。为了在超高频（UHF）范围内沿电子纺织品过滤和控制信号传播，将传统超材料传输线与绣制的超材料颗粒进行了比较。所提出的设计基于在毡基上加载一个或几个开口环谐振器（SRR）的传输线。为了探索物理参数与滤波器性能特征之间的关系，提出了基于传输矩阵对滤波器组成部件描述的理论模型。理论预测、电磁模拟和测量结果之间具有良好的一致性。实验结果表明，紧凑型绣制超材料电子纺织品的阻带水平高于-30dB。验证结果证实刺绣是一种在可穿戴应用中获得定制电磁特性（如滤波）的有用技术。
