  • Multi mode filter for realizing wide band using capacitive coupling / inductive coupling and capable of tuning coupling value
    Patent number: 9184479
    Abstract: A multi-mode filter for realizing wide band using capacitive coupling and inductive coupling and capable of tuning coupling value is disclosed. The multi-mode filter includes a housing; a first cavity and a second cavity formed in the housing; a first resonator located in the first cavity, a second resonator located in the second cavity, a wall configured to separate the first cavity from the second cavity; and a first coupling element, wherein a groove is formed between the housing and the wall, the first coupling element is inserted in the groove in crossing direction to the wall, one part of the first coupling element is disposed in the first cavity, another part of the first coupling element is disposed in the second cavity, and the first coupling element is connected to a ground.
