摘要 提出了超宽带Koch分形缝隙天线的设计方法。通过引入Koch分形,可显著缩小超宽带缝隙天线的体积,同时还可以通过调整分形缝隙的边界花样长度获得灵活的陷波功能。给出了Koch分形天线的设计过程,通过理论计算和尺度放大实验,研究了天线的陷波性能。实验与理论计算的良好吻合表明文中提出的方法是正确有效的。 This paper propose a method to design a ultra-wideband （UWB） Koch fractal slot antenna. By employing Koch fractal shape wide slot, the volume of the antenna may be decreased drastically. By adjusting the length of the Koch fractal＇ s edge, flexible frequency notched function can be achieved. The designing procedure of the antenna is also presented. The antenna and its large-scaled prototypes are evaluated experimentally for their frequency notched function. The well-accordance between numerical and experimental results shows that the method proposed is correct and effective.
