    摘要:

    针对NRD波导中不同半径的弯波导之间的耦合特性,提出了一种新的通用的分析方法,当耦合结构分别简化为非对称结构(即直波导与弯波导耦合)和对称结构(即两个半径相同的弯波导的耦合)时,该方法也可相应简化,与已有的分析结果完全一致。本文还就不同半径的弯波导构成的耦合器的频率响应和带宽特笥,在60GHz时给出实验验证,证实了本文所提方法的通用性和有效性。

    Abstract:

    With regard to the coupling characteristics of multiple kinds of bending waveguides of NRD waveguides with different curvature radii, a novel and general analysis method was presented. When the coupling structures become the asymmetric (coupling of a straight waveguide with a bending one) or the symmetric (coupling between two bending waveguides of the same curvature radii) structures, the new method can be simplified, respectively, to be in full accordance with the reported results. Experiments were done at 60GHz for the frequency responses and the bandwidth characteristics of couplers by using bending waveguides with various curvature radii. And the generality and validity of the method were verified.
