摘　　要：采用缺陷地结构和加载枝节贴片的方法,设计了一种结构简单的新型对偶复合左右手传输线,并深入研究了其电磁特性。采用Bloch-Floquet理论和全波仿真软件推导并计算了该结构的色散曲线,理论和仿真结果吻合较好,证明了该结构为对偶复合左右手传输线结构。给出了该结构的等效电路模型,并提取了相应电路结构参数。采用电磁扫描仿真,分析了结构参数的变化对其电磁特性的影响。相对于文献[8～9]中结构,该结构相对简单,参数易于调节;同时,该结构具有对称性,能够更好的应用于微带天线的设计。A novel dual-composite right/left-handed transmission line is proposed in this paper based on the reference [8-9], and its electromagnetic characteristics are investigated. The dispersion curve of the pro-posed structure has been derived by using Bloch-Floquet theory and simulator, and the D-CRLH is proved. The equivalent circuit model is given, and the extractive parameters of the model are extracted. The influ-ences of the change of the structure parameters on its electromagnetic characteristics are analyzed by An-soft HFSS10. Compared with the structure in reference [8-9], the proposed structure is simpler,and is easy to adjust in its parameters. What is more, the proposed structure is of symmetrization, and can be used in the design of microstrip antenna.
