摘　　要：文章针对移动通信系统、射频识别系统、超宽带通信系统对天线的性能要求,使用耳蜗螺旋仿生辐射结构作为阵元天线,谢尔宾斯基分形结构作为阵列排布结构,设计了一款分形阵列螺旋仿生超宽带天线,并对其工作性能进行了测试。测试结果表明,该款天线的工作频带范围为0.537~13.158 GHz,工作带宽为12.621 GHz,带宽倍频程为24.51,回波损耗最小值为-32.08 d B。该款天线完全覆盖了移动通信系统所有工作频段、射频识别系统频段、超宽带系统频段。因此,它是一款性能很好的超高兼容性通信天线。A fractal array spiral bionic ultra wideband antenna was designed to meet with the requirements of the antenna's performances including mobile communication systems,radio frequency identification systems and ultra-wideband communication systems.As an element of the antenna,the cochlea spiral bionic and the Sierpinski fractal array structure were applied to design the antenna.Meanwhile,the performance of the antenna was detected.The results indicated that the antenna's working frequency range could be 0.537 GHz to 13.158 GHz,the bandwidth was up to 12.621 GHz,the bandwidth octave was 24.51,and the minimal return loss was-32.08 dB.The working frequency of this antenna completely covered all bands of the mobile communication systems,the radio frequency identification systems,and the ultra-wideband systems.Therefore,it is a highly compatible communication antenna with excellent performances.
