摘　　要：设计了一种新型分形结构,并将其应用于低剖面天线中.该分形天线中心频率为915MHz,工作带宽为20MHz,垂直极化.将此新型分形结构应用于介质板顶层的开路部分,可有效减小矩形介质板的尺寸.分形天线的尺寸比参考天线的尺寸减小了15%,小型化效果明显.根据仿真加工了天线实物,仿真和实测结果都证明了该方案的可行性.A novel fractal iteration technique has been applied to a low-profile miniaturized monopole antenna. The resonant frequency of the antenna is 915 MHz and the bandwidth is about 20 MHz with vertical polarization. The fractal shape is applied to the open-circuited segment of the substrate to reduce the dimension of the substrate. At the same resonant frequency, the substrate dimension of the fractal antenna is 15% smaller than that of the reference antenna. An antenna prototype is fabricated based on the simulation. The simulated and tested results prove that the design is feasible.
