摘要
设计了一种基于Minkowski分形的磁电偶极子天线。在传统磁电偶极子天线的基础上,通过加载Minkowski分形结构以延长电流路径,可有效地降低天线的中心频率,实现天线的小型化设计。该天线采用2阶分形结构,通过仿真分析得出:天线相对带宽可达53%(S_(11)小于-10 dB),在1.65~2.84 GHz工作频带内,E面和H面的方向图基本一致,具有低交叉极化特性,与分形前相比,天线体积缩小19.5%。
A magnetoelectric dipole antenna based on Minkowski fractal is designed.On the basis of traditional magnetoelectric dipole antenna,the current path is extended,by loading the Minkowski fractal structure,the center frequency of the antenna can be effectively reduced,and the miniaturized design of the antenna can be realized.The antenna adopts a second-order fractal structure.Simulated results show that the relative bandwidth of the antenna is up to 53%(S_(11)<-10 dB)in working band of 1.65~2.84 GHz.The pattern of E-plane and H-plane are basically the same,with low cross-polarization characteristics.The antenna volume is reduced by 19.5%compared to that before fractal.
