Abstract: 
A pattern reconfigurable antenna array for 5.8 GHz wireless body area network (WBAN) applications is proposed in this paper. The antenna array consists of a radiation component and a controller component. The radiation component comprises four planar F-shaped antennas, which are located on the four corners of the upper layer and are rotated 90° anticlockwise from each other. The controller component is located in the lower layer and includes a four-port controllable network. An omnidirectional radiation pattern tangent to the human body surface and a directional radiation pattern normal to the human body surface can be obtained by controlling the PIN diodes, which are integrated in this controllable network. Measurements of impedance bandwidth, radiation pattern, and gain are performed when the array is mounted on the human body or forearm phantom, and the results agree with the simulation. Specific absorption rate (SAR) values for both radiation modes, and beam switch ability are also simulated to ensure the practicability of this array.

摘要:本文提出一种适用于5.8 GHz WBAN应用的方向图可重构天线阵列。天线阵列由辐射组件和控制网络组件组成。辐射组件包括4个平面F型天线,它们位于上层的4个角上,彼此逆时针旋转90°。控制网络组件位于底层,包括一个4端口可控网络。通过控制集成在可控网络中的PIN二极管,可以获得与人体表面相切的全向辐射图和与人体表面垂直的定向辐射图。我们测量了阵列安装在人体或前臂假体上时的阻抗带宽、辐射模式和增益,实验结果与仿真结果一致。同时仿真了两种辐射模式下的电磁波吸收比值(SAR)和波束切换能力,以确保该阵列的实用性。
