| 摘 要： | 利用分形结构的自相似性，通过在微带信号线两侧引入“H”型分形，研制了一种微带电磁带隙结构．该结构在0～15GHz频率范围内显示出了多禁带和通带的频带特性．实验中运用传统的印刷电路板工艺制作了这种微带电磁带隙结构，并通过矢量网络分析仪和时域有限差分方法分别得到了实验结果和模拟结果，证实了这种微带电磁带隙结构具有多禁带和通带的频带特性．

| Abstract: | A microstrip electromagnetic bandgap structure(EBG) that showed multiple gaps and pass bands for electromagnetic waves at 0~15 GHz frequency range is presented.This structure showed the characteristic of multiple gaps and pass bands because of the introduction of the H-shaped fractal with self-similar property.And prototype of EBG is fabricated with conventional low-cost printed circuit board techniques.The experimental result is measured by Anritsu 37269C Vector Network Analyzer and the simulated result is obtained by finite different time domain(FDTD) method.The characteristic of multiple gaps and pass bands is proved experimentally and theoretically. |
