Sierpinski分形天线的结构具有自相似性,从而天线具有良好的多频带特性。文中主要研究了Sierpinski分形天线频带位置随天线张角和比例因子变化的一般规律,并简要的分析了Sierpinski分形天线阵,绘出了其远场方向图,讨论了其低副瓣特性。

The structure of the Sierpinski fractal antenna is self-similar,so it has a good multi-band characteristic.In this paper,the dependence of its frequency bands on the flare angle and the scale factor are investigated.This paper also analyses briefly the Sierpinski fractal antenna array,and its far-field radiation patterns are plotted to show the low-sidelobe lever characteristic of this antenna array.
