摘要
首先,采用时域有限差分方法建立超宽带(UWB)传输系统;然后,对头部穿戴设备模型中的输入阻抗特性、传输特性以及电场分布进行分析,明确设备间的UWB传输机制;最后,对人体模型进行简化,并对比简化前后模型的路径损耗。结果表明本研究提出的UWB传输系统路径损耗低,传输特性稳定,对面向头部可穿戴设备体表传输技术的发展具有重要意义。
The finite difference time domain method is used to establish the ultra wide band(UWB)transmission system;the input impedance characteristics,transmission characteristics,and electric field distribution in the head wearable device model are analyzed to clarify the UWB transmission mechanism between the devices;and the path loss before and after the simplification of the human body model is compared.The results show that the proposed UWB transmission system has low path loss and stable transmission characteristics,which is of great significance for the development of body surface transmission technology for head wearable devices.
