A unique metamaterial-based UWB band notched textile antenna for Body Area Network (BAN) is created in this paper, with an operational frequency range of 3–11 GHz, spanning the Ultra Wide Band (UWB) band (3.1–10.6 GHz). Using the textile material Jeans, which has a permittivity of 1.67, the antenna’s size is lowered. To enhance the impedance bandwidth, the ground plane is made of partially conductive material and is rectangular. The hexagonal slot is used to increase the electric field dispersion along the borders of the hexagonal slot, which improves bandwidth. The gain of the UWB of the antenna maximum is obtained at 7.52 dB and minimum is obtained at 5.25 dB. The VSWR of the UWB of the antenna maximum is obtained at 1.92 and minimum is obtained at 1.45. The fabrication uses a Denim substrate with a thickness of 1 mm and a microstrip feed. The designed antenna is investigated for its return loss and gain characteristics.

用于医疗保健监控系统的纺织品 UWB 天线性能

本文创建了一种用于体域网 (BAN) 的独特的基于超材料的 UWB 带缺口纺织天线，其工作频率范围为 3-11 GHz，跨越超宽带 (UWB) 频带 (3.1-10.6 GHz)。使用介电常数为 1.67 的纺织材料牛仔裤，天线的尺寸减小了。为了提高阻抗带宽，接地层由部分导电材料制成并且是矩形的。六角槽用于增加沿六角槽边界的电场色散，从而提高带宽。天线的 UWB 增益最大值为 7.52 dB，最小值为 5.25 dB。天线 UWB 的 VSWR 最大值为 1.92，最小值为 1.45。该制造使用厚度为 1 mm 的 Denim 基板和微带馈电。
