摘　　要：文章提出了一种新型的V形微带曲折线慢波结构,利用电磁场仿真软件HFSS分析其结构参数对色散特性及耦合阻抗的影响,并对介质衬底结构形式进行了改进。结果表明,改进后的结构提高了耦合阻抗,但对色散特性没有明显影响。The new V-shaped microstrip meander-line slow wave structure was put forward.The effects of structural parameters on the dispersion characteristics and coupling impedance were analysed by the electromagnetic simulation software HFSS,and the slow wave structure supported by dielectric slab was improved.The results show that the improved structure can increase the coupling impedance,but has not obvious influence on the dispersion characteristics.
