针对无线通信等领域对频率切换和频率自动跟踪的应用需求,设计了一款新型可重构天线。该天线由矩形贴片天线和2片寄生矩形金属条组成,在矩形贴片天线和寄生金属条之间焊接了6只PIN二极管,控制6只PIN二极管的导通和关断状态实现天线在2.17 GHz和2.54 GHz工作频点之间切换,实现天线频率可重构。一旦发射端频率发生改变,该天线的频率跟踪控制器利用检波器实时检测天线接收功率值,并通过功率阈值判断发射频率变化,实时改变天线工作频率实现频率自动跟踪。介绍了天线结构和频率跟踪控制器设计,加工制作了该可重构天线样品,实验测试验证了该天线的频率切换和频率自动跟踪功能。
Abstract:For the application requirements of the frequency switching and the automatic frequency tracking in wireless communication, a novel reconfigurable antenna is proposed.The antenna consists of a rectangular patch antenna and two parasitic rectangular metal strips.Six PIN diodes are welded between the rectangular patch antenna and the parasitic metal strip.By controlling the ON or OFF states of those PIN diodes, the proposed antenna is able to switch its working frequency between 2.17 GHz and 2.54 GHz, and thus the frequency reconfiguration is realized.Based on a frequency tracking controller that uses a detector to detects the receiving power in real time, once the transmitter frequency has been changed, the antenna is able to discover the frequency change according to a preset power threshold, and automatically switches its working frequency to track the transmitter frequency.The configuration of the proposed antenna and the design of the frequency tracking controller are introduced, moreover a prototype is fabricated and measured.The results show that the frequency switching and automatic frequency tracking of the antenna.
