    Abstract: The comb-line filter is formed by a housing and a plurality of U-shaped resonator elements each having one end connected directly to the grounded housing and the other end connected to the housing through a lumped capacitor. Each of a first set of partitions is disposed between the legs of the U-shaped elements to form a coaxial structure therewith and each of a second set of partitions is disposed either between adjacent resonator elements, between adjacent lumped capacitors, or between an adjacent resonator element and lumped capacitor to control the coupling between resonant cells.

    Abstract translation: 梳状滤波器由外壳和多个U形谐振元件形成，每个U形谐振元件的一端直接连接到接地的外壳，另一端通过集总的电容器连接到外壳。 第一组分隔件中的每一个都设置在U形元件的腿部之间以与其形成同轴结构，并且第二组分隔件设置在相邻的谐振元件之间，相邻的集总电容器之间，或相邻的谐振器 元件和集总电容器来控制谐振单元之间的耦合。
