文中提出了一种采用金属条带代替金属脊结构的缝隙波导传输线结构。为了简化缝隙波导结构的分析与设计,对理想PEC-PMC平面结构和PEC-AMC平面结构的缝隙波导的传输特性进行了分析,并证明了两种方法在分析缝隙波导结构时具有等效性。利用这一特性,可以降低分析复杂缝隙波导结构时的计算复杂度。
In this paper, a slotted waveguide transmission line structure using metal strips instead of metal ridges is proposed. In order to simplify the analysis and design of slot waveguide structure, the transmission characteristics of slot waveguide in ideal PEC-PMC plane structure and PEC-AMC plane structure are analyzed and the equivalence of the two methods in the analysis of slot waveguide structure is proved. With this feature, the computational complexity of analyzing complex slot waveguide structures can be reduced.
