摘要

本文报道了一种由细同轴电缆馈电的电纺织天线,该天线基于类单极子元件和在地平面上具有三角形过渡的矩形槽。该结构类似于印刷槽天线,带有两层电子纺织层和用作电介质的普通毛毡。原型是为一个孤立的天线和用户肢体附近制造和测量的。天线的中心频率为2.45 GHz。采用简化仿真模型模拟了用户肢体对天线性能的影响。为了提高天线的辐射和总效率,设计中采用了EBG激励结构。对该结构进行了数值模拟,并对其在人体附近的佩戴场景进行了测量。

Electro-textile printed slot antenna over finite EBG structure
This paper reports an electro-textile antenna fed by a thin coaxial cable, based on a monopole like element and a rectangular slot with a triangular transition on a ground plane. The structure resembles a printed slot antenna with two electro-textile layers and common felt used as dielectric. Prototypes were fabricated and measured for an isolated antenna and in the vicinity of a user's limb. The antenna was designed for central frequency 2.45 GHz. A simplified simulation model was used to emulate the effect of the user's limb on the antenna performance. To improve antenna radiation and total efficiency an EBG inspired structure was included in the design. The new structure was numerically simulated and measured in wearing scenario in the vicinity of the human body.
