  • Patent number: 11955681
    Abstract: A band-pass filter includes a first input/output port, a second input/output port, a plurality of resonators, and a multilayer stack. The multilayer stack includes a plurality of stacked dielectric layers. Each of the resonators is an open-ended resonator formed of a conductor line in the multilayer stack. Each of the resonators includes a resonator conductor portion including a first line part and a second line part located away from each other in a direction orthogonal to a stacking direction of the plurality of dielectric layers, and a third line part connecting the first line part and the second line part. The first to third line parts extend to surround a space between the first line part and the second line part.

  • Patent number: 9200694
    Abstract: A partitioning wall is integrally formed to a rubber elastic body, partitioning second main liquid chambers. An upper outer peripheral member and a lower outer peripheral member are positioned in the axial direction by a partitioning wall positioning member disposed in the second main liquid chambers. The partitioning wall is retained to the peripheral inside of a retaining member in an axial direction (S) compressed state.
