摘　　要：提出了一款应用于L波段、S波段和C波段的六边形分形宽带微带天线,该天线采用二阶六边形Sierpinski分形结构作为辐射贴片,使用微带馈电技术进行馈电。通过仿真分析与模型优化,天线的最终尺寸为36 mm×28 mm×1.6 mm,-10 dB阻抗相对带宽为150.3%(1.10~7.76 GHz),在1.10 GHz处有最大峰值增益7.80 dB。该天线具有结构简单、体积小、带宽大、增益良好的特点,可以适用于各种宽频带通信系统中。A hexagonal fractal broadband microstrip antenna for L-band,S-band and C-band is proposed.The second-order hexagonal Sierpinski fractal structure is used as the radiation patch,and the microstrip feeding technology is used for feeding.Through simulation analysis and model optimization,the final size of the antenna is 36 mm×28 mm×1.6 mm,the relative bandwidth of-10 dB impedance is 150.3%(1.10~7.76 GHz),and the maximum peak gain is 7.80 dB at 1.10 GHz.The antenna has the advantages of simple structure,small size,large bandwidth and good gain,which can be used in various broadband communication systems.
