摘要

本研究提出了一种用于无线体域网络(WBAN)的低姿态自然超宽带(UWB)天线。该天线可以有效地减小人体的接近效应，三单极子结构设计成规则的矩形图案。低成本的FR-4环氧基板材料与同轴进料一起构建，实现了超宽带特性。这种结构可以产生3GHz到10GHz的带宽，满足WBAN应用中更高的数据传输要求。在满足S/C/X频段频率的3.1GHz、5.1GHz、8GHz和8.8GHz谐振频率下，回波损耗和驻波比分别>-20dB和<2。该天线显示出单向辐射方向图，效率在45 ~ 75%之间，并产生中等的总带宽增益。这些特性是WBAN通信所需要的。

A Low Profile UWB Antenna for Wireless Body Area Network: Design and Analysis

A low profile nature ultra wide-band (UWB) antenna for wireless body area network (WBAN) is presented in this research work. This antenna can effectively reduce a proximity effect of human body and tri-monopole structure is designed with regular rectangular pattern. The low cost FR-4 epoxy substrate material is constructed along with coaxial feeding achieves the UWB characteristics. This proposed structure produces a bandwidth from 3GHz to 10GHz, which is highly required for higher data transmission for WBAN application. The return loss and VSWR is achieved >-20dB and <2 for the resonant frequencies of 3.1GHz, 5.1GHz, 8GHz and 8.8GHz which is also satisfy the S/C/X band frequencies. This antenna shows that unidirectional radiation pattern with efficiency between 45 to 75% and produce moderate gain of overall bandwidth. These features are highly required and suitable for WBAN communication.
