摘要
本文提出了一种圆盘形,辐射贴片类似六瓣雪花状的频率及方向图可重构天线。该天线由位于中心的馈电圆盘,与圆盘同心的圆环,以及围绕圆环对称分布的六个完全相同的枝节组成。通过控制十二个PIN开关的通断,该天线可分别工作在频段4.05GHz-7.57GHz和频段3.43GHz-3.76GHz,且在每个工作频带内可以实现六种定向方向图的变化。
A disc-shaped frequency and pattern reconfigurable antenna with six snowflake patches is proposed. The antenna consists of a feeding disc which located in the center of the top layer and a concentric ring which surrounded by six uniform strips. By controlling twelve pin diodes, the antenna operates at two frequency band of 4.05GHz-7.57 GHz and 3.04GHz-3.76 GHz with the reconfigurability of the main beam in six directions with 60o steps in azimuth plane.
