所谓的“可穿戴纺织品系统”旨在通过增强穿戴者的功能来提高生活质量。具有监测生物信号并与环境通信的能力的服装可以例如提供关于人的健康状态的连续信息。这些数据可以是有价值的医疗输入，也可以在灭火等紧急行动中，它可以成为决定消防员可操作性的工具。然而，与环境的无线通信需要天线。当保持纺织品特性（例如柔性和舒适性）是一个问题时，天线应该被制造成可完全集成到服装中，并且因此由纺织品材料制造。本文展示了在专用2.45 GHz频率范围内工作的天线设计中使用纺织材料的可行性。我们使用了一个商业电磁场模拟器来设计微带贴片天线制造的导电（electrotextiles）和非导电纺织材料。对于天线和接地平面，评估了容易获得的电纺织品：FlecTron（R）、Shieldit（TM）Super和Zelt.，而羊毛织物用于天线基板。我们发现这种天线原型的效率超过75%，与传统的非纺织品天线相当。这项研究是设计纺织天线的第一步，为新一代通信服装铺平了道路。
So-called "wearable textile systems" are intended to improve the quality of life by enhancing the wearer's functionalities. Garments having the ability to monitor biosignals and communicate with the environment can, for example, provide continuous information about a person's state of health. These data can be valuable medical input, but also in emergency operations such as fire extinguishing, it can be a tool to decide on the operability of the fire fighter. However, wireless communication with the environment requires antennas. When preserving textile properties such as flexibility and comfort is an issue, antennas should be made fully integratable into garments and, thus, manufactured from textile material. This paper shows the feasibility of the use of textile materials in the design of antennas working in the dedicated 2.45 GHz frequency range. We used a commercial electromagnetic field simulator to design microstrip patch antennas fabricated from both conductive (electrotextiles) and nonconductive textile material. For the antenna and the ground plane, readily available electrotextiles were assessed: FlecTron (R), Shieldit (TM) Super and Zelt., while a fleece fabric was used for the antenna substrate. We found that such antenna prototypes had an efficiency of more than 75%, which was comparable to conventional non-textile antennas. This research is an initial step in designing textile antennas and paves the way for a new generation of communicating garments.
