摘要
对一种超宽带平面圆形单极子印刷天线提出改进方法,通过在圆形贴片上蚀刻分形几何中的Sierpinski三角,使天线满足在2.8～15.1GHz的超宽带频带要求,并且实现了4.5～5.9GHz的频率缺口的功能,大大提高了天线的抗干扰性.通过仿真表明,天线的远场辐射方向图,驻波比VSWR均满足要求,并且分形特有的尺寸缩减性实现了超宽带天线的小型化.为分形天线的几何参数与电参数之间关系的研究提供理论依据与数据支持.
This paper puts forward an improved method for an ultra-wideband planar monopole antenna. By etching in the circular patch with the fractal geometry of the Sierpinski triangle, the antenna could meet the requirements of the UWB （ultra wideband） frequency between 2.8-15.1 GHz, and achieved a frequency of the gap function between 45~5.9 GHzThis greatly increased the anti-interference performance of the antenna. The simulation showed the antenna＇s far- field radiation pattern~ The standing wave ratio VSWR requirements are met, and the unique fractal characteristics reduced the size of the ultra wideband antenna. This paper provides a theoretical basis and data support for the research of the relationship between geometric parameters and electrical parameters of fractal antennae.
