This paper analysed the effects of bending on the performance of a textile antenna wherein the antenna under test was made of felt substrate for both industrial, scientific, and medical (ISM) band and WBAN applications at 2.45 GHz. Moreover, the conductive material was used for the patch, and the ground plane used a 0.17 mm Shieldit textile. Meanwhile, the antenna structure was in the form of rectangular, with a line patch in between elements to abate the mutual coupling effect. The measured operating frequency range of the antenna spanned from 2.33 GHz to 2.5 GHz with a gain of 4.7 dBi at 2.45 GHz. In this paper, the antenna robustness was examined by bending the structure on different radii and degrees along both X- and Y-axis. Next, the effects on return loss, bandwidth, isolation, and radiation characteristics were analysed. This paper also discovered that the antenna’s performance remained acceptable as it was deformed, and the measured results agreed well with the simulation.

无线体域网 (WBAN) 应用不同弯曲条件下的可穿戴天线研究

本文分析了弯曲对纺织天线性能的影响,其中被测天线由毛毡基材制成,适用于工业、科学和医疗 (ISM) 频段以及 2.45 GHz 的 WBAN 应用。此外,贴片使用导电材料,接地面使用 0.17 mm Shieldit 织物。同时,天线结构为矩形,元件之间有线贴片,以减少相互耦合效应。测得的天线工作频率范围从 2.33 GHz 到 2.5 GHz,在 2.45 GHz 时增益为 4.7 dBi。在本文中,通过沿X 轴Y轴以不同半径和角度弯曲结构来检查天线的稳健性-轴。接下来,分析了对回波损耗、带宽、隔离度和辐射特性的影响。该论文还发现,天线变形后的性能仍然可以接受,并且测量结果与仿真结果非常吻合。
