摘　　要：设计了一种新颖的多频带天线。给出了传统矩形波导的归一化宽度公式,并介绍了Koch曲线的基本概念,利用电磁仿真软件HFSS对天线的电特性进行仿真优化。Koch分形结构具有自相似性,故天线具有良好的多频带特性,通过讨论,设计出了3个谐振频率,分别为3.9 GHz,4.5 GHz和13.4 GHz,而且该天线面积小,约为78.7 mm×40 mm。A novel multi - band antenna is designed. An experimental formula is given for the normalized width of the traditional rectangular waveguide,and the basic accept of Koch curve is introduced. The parameters of antenna are simulated and optimized by the simulator of HFSS. The structure of the Koch fractal antenna is self - similar;so it has a good multi - band characteristics, the multi- band characteristics of antenna is also discussed in the paper, three resonant frequency are designed, which are 3.9 GHz,4. 5 GHz and 13. 4 GHz. And the antenna which is about 78.7 mm×40 mm is small.
