摘　　要：针对第二代~第五代移动通信系统对天线的性能要求,文中将矩形环分形结构、康托尔分形结构、谢尔宾斯基分形结构、十字分形结构相结合,设计了一款能够同时覆盖第二代~第五代移动通信频段的复合分形移动通信天线。仿真和实测结果表明,该天线的工作频带范围为0.751~6.353 GHz,工作带宽为5.602 GHz,天线具有全向辐射特性。该款天线实现了对第二代~第五代移动通信系统的兼容,具有尺寸小、回波损耗低、工作带宽大等优点。According to the requirements of the second generation to the fifth generation mobile communication system to the antenna＇s performance,combined rectangular ring fractal structure,Cantor fractal structure,Sierpinski fractal structure and cross fractal structure,designed a composite fractal mobile communication antenna that can cover the second generation to the fifth generation mobile communication band at the same time. The result of simulation and test indicate that the antenna＇s working frequency range is 0. 751 - 6. 353 GHz,the antenna＇s working bandwidth is5. 602 GHz,the antenna has omni directional radiation characteristics. This antenna realized the compatible of the second generation to the fifth generation mobile communication system,and has the advantages of small size,low return loss and wide working bandwidth.
