摘要

本文研究了一种带腔背隙天线的定位传感器的设计与验证。传感器节点使用Decawave DW1000芯片组，以及一个基本传感器、一个微控制器和一个闪存卡。它设计在机械柔性印刷电路板(PCB)上，其中组件边缘和过孔对齐形成刚性线。提出了一种衬底集成波导(SIW)天线的设计方案:一种结合了硫化橡胶泡沫和电织物的空腔背槽天线。利用系统保真系数(SFF)中的脉冲变形和距离估计误差(DEE)中的相移分析了脉冲无线电超宽带(IR-UWB)定位。身体测量显示一切正常。

Design and Verification of IR-UWB Localisation Sensor Node with Cavity-Backed Textile Antenna

This paper handles the design and verification of a localisation sensor with a cavity-backed slot antenna. The sensor node uses a Decawave DW1000 chipset, together with a basic sensor, a microcontroller and a flash memory card. It is designed on a mechanically flexible Printed Circuit Board (PCB), where component edges and vias are aligned forming rigid lines. As antenna a Substrate Integrated Waveguide (SIW) design is proposed: a cavity-backed slot antenna combining vulcanised rubber foam and electrotextile. Impulse-Radio Ultra-Wideband (IR-UWB) localisation is analysed by the pulse deformation in the System Fidelity Factor (SFF) and the phase shift in the Distance Estimation Error (DEE). On-body measurements show that everything works fine.
