Sierpinski分形天线特性分析

Analysis of the Characteristics of Sierpinski Fractal Antenna

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.
