Abstract

In the last decade, body-centric communications have taken on great relevance in the field of Wireless Mobile Communications and with a wide range of applications, such as medical, emergency, military, geopositioning, in the logistics industry, among others. An essential part of these applications is carried out by wearable antennas. This paper presents the design of a wearable patch antenna, using materials and accessories for clothing. The antenna has been designed to work at the 4.15 GHz frequency of the Band C (satellite systems) and which has also been studied to be implemented in 5G technologies. The radiant patch was designed with a metal button (used as an accessory in blue jeans), and the simulated dielectric substrate was made of the same jean textile material with a relative permittivity of 1.6 and a thickness of 1.56 mm. Results of the radiation pattern, gain, reflection coefficient, and efficiency under numerical analysis with specialized software. The good results of the gain stand out, being this one of 8 dBi, and the efficiency of 76.88 % was obtained.

基于服装材料的贴片天线设计:仿真研究

在过去十年中，以身体为中心的通信在无线移动通信领域具有很大的相关性，并具有广泛的应用，如医疗、应急、军事、地理定位、物流行业等。这些应用的一个重要部分是由可穿戴天线实现的。本文介绍了一种可穿戴贴片天线的设计，采用服装材料和配件。该天线被设计为在C波段(卫星系统)的4.15 GHz频率上工作，并已研究在5G技术中实现。辐射贴片设计为金属扣(作为蓝色牛仔裤的附件)，模拟介质衬底采用相同的牛仔纺织材料，相对介电常数为1.6，厚度为1.56 mm。用专门的软件对辐射方向图、增益、反射系数和效率进行了数值分析。结果表明，该增益为8 dBi，效率为76.88%。
