Abstract:
1. A multi-mode filter comprising: a housing; a cavity formed in the housing; a resonator located in the cavity; at least one connector formed through a side wall of the housing; and at least one coupling element connected to the at least one connector in the cavity, the at least one coupling element coupling the at least one connector with the resonator, wherein the at least one coupling element is located between one of the at least one connector and the resonator, and the at least one coupling element is fixed at a bottom part of the cavity, and wherein, each of the at least one coupling element is “T” shaped when viewed from a front with respect to a viewing direction oriented from the resonator to one of the at least one connector, and is “L” shaped when viewed from a side direction orthogonal to the viewing direction oriented from the resonator to one of the at least one connector.
