摘要 在研究了微带型曲折线慢波结构色散特性、耦合阻抗等特性参数的分析方法基础上,利用电磁场仿真软件MAFIA和Microwave Studio对其进行模拟计算。对影响慢波电路特性的结构参数如微带宽度和微带厚度对其冷测特性的影响进行了仿真和分析,同时对介质杆支撑的曲折线慢波电路进行了分析。结果表明,微带宽度对其特性影响较为显著而微带厚度的改变影响不大,介质杆代替介质板使慢波电路的特性参数产生了较大的变化。 With the electromagnetic simulation software MAFIA and Microwave Studio, method of simulating dispersion characteristics and coupling impedance of microstrip meander-line slow wave structure is described. The performance of the microstrip meander-line for different structural parameters is calculated and the slow wave structure supported by dielectric slab is analyzed. The results showed good agreement between simulation and theory, and the width of microstrip has more effects on the cold characteristics.
