摘要

本文设计并实现了适用于体域网络的可穿戴式超宽带天线。阶梯圆形辐射贴片、微带馈线和梯形地板构成了天线的大部分。通过使用液晶聚合物（一种柔性材料）作为电介质基板，实现了良好的弯曲质量。设计的天线尺寸为 30 mm × 35 mm × 0.1 mm，上面刻有两个 C 形槽，可在 3.20-4.10 GHz 和 5.19-5.98 GHz 频段实现陷波功能。其工作频率范围为 1.96-11.61 GHz，对人体的比吸收率小于 2 W/kg。测试结果表明，利用天线阻抗和辐射特性可以实现超宽带体域网络系统。

Liquid Crystal Polymer-Based Flexible Trap Ultra-Wideband Antenna Design

The wearable ultra-wideband antenna that is appropriate for body area networks is designed and implemented in this article. Stepped circular radiation patches, microstrip feeders, and trapezoidal floors make up the majority of the antenna. Good bending qualities have been attained by using liquid crystal polymer, a flexible material, as a dielectric substrate. An antenna measuring 30 mm × 35 mm × 0.1 mm was designed with two C-shaped slots etched on it to achieve notch function in the 3.20–4.10 GHz and 5.19–5.98 GHz frequency bands. Its working frequency range was 1.96–11.61 GHz, and its specific absorption rate for the human body was less than 2 W/kg. The test findings demonstrate that ultra-wideband body area network systems can be implemented using the antenna impedance and radiation characteristics.
