摘要

提出了一种用于认知无线电应用的频率可重构天线系统。该天线结构由传感天线和频率可重构天线系统组成。传感天线扫描信道以发现频带，而可重构部分正在调谐以在这些频带内通信。可重构天线由5个不同的频段组成，频率范围从2.1 GHz到10.6 GHz。频率敏捷性是通过贴片天线的旋转运动来实现的。旋转由安装在天线结构背面的步进电机控制，电机的旋转运动由连接微控制器的MEMS开关控制。频率可重构天线具有制作简单、安装方便、覆盖超宽带等优点。

A frequency reconfigurable antenna design for UWB applications

This paper proposes a frequency reconfigurable antenna system designed for cognitive radio applications. The antenna structure consists of a sensing antenna and a frequency reconfigurable antenna system. The sensing antenna scans the channel to discover frequency bands while the reconfigurable section is tuning to communicate within these bands. A reconfigurable antenna consists of five different patches and there frequencies cover from 2.1 GHz to 10.6 GHz. The frequency agility is achieved via a rotational motion of the patch antennas. The rotation is controlled by a stepping motor mounted on the back of the antenna structure and the motor's rotational motion is controlled by MEMS switch connected to a microcontroller. A frequency reconfigurable antenna offers many advantages such as easy fabrication, suitability for installation and coverage spectrum UWB (Ultra Wideband).
