摘要

本文设计了一种适用于2.45 GHz ISM频段WBAN应用的纺织贴片天线。天线采用牛仔布作为基材，导电织物用于接地面和辐射层。本文的主要目的是分析牛仔布性能的典型偏差和贴片散热器尺寸对天线性能的影响。分析中考虑的参数是牛仔布的相对介电常数和厚度以及矩形贴片散热器的宽度和长度。利用电磁仿真得到的天线反射系数，研究了天线中心工作频率与这些参数的关系。推导了单弹设计的经验法则，并应用于矩形贴片天线的设计。制作了天线样机并进行了测量，结果表明天线在2.45 GHz处的10 dB阻抗为4.8%，与仿真结果吻合较好。

Parametric study of rectangular patch antenna using denim textile material

This paper presents a textile patch antenna designed for WBAN applications at 2.45 GHz ISM band. The antenna uses denim as substrate and conductive fabric for the ground plane and radiator layers. The main purpose of this paper is to analyze the influence of typical deviation of denim properties and patch radiator dimensions on the performance of the antenna. The parameters considered in the analysis are the relative permittivity and thickness of denim and the width and length of the rectangular patch radiator. The dependence of the central operation frequency of the antenna on those parameters was studied using the antenna reflection coefficient obtained from EM simulations. Rules of thumb for one-shot design were derived and applied to design a rectangular patch antenna. An antenna prototype was fabricated and measured, demonstrating a 10 dB impedance band of 4.8 % centered at 2.45 GHz, in good agreement with simulated results.
