| 摘 要： | 结合分形理论的优点，仿真设计了2种基于分形技术的微带天线。这2种天线均采用正六边形分形迭代结构，分别使用微带线和共面波导馈电。通过数值仿真，对天线的阻抗特性和方向图进行了研究，结果表明这2种分形天线的阻抗带宽均达到了90％左右，并且在整个工作频段内具有良好的辐射方向性。同时分形结构的引入，实现了天线的小型化。

| Abstract: | Two fractal microstrip antennas are designed based on the advantages of fractal theory. Both antennas explore iterative hexagon fraction, and one uses microstrip for feed, the other uses coplanar waveguide （CPW） for feed. Through numerical simulation, a research on the impedance, radiation pattern of the antenna is provided. Experiment results show that the impedance bandwidth all reaches about 90% , and has good radiation properties in the whole working bandwidth. Simultaneously by introducing the fraction antenna miniaturization is also realized. |
