Abstract
The present invention achieves a filter that makes it possible to easily adjust a center frequency of a pass band. A filter (1) includes a post-wall waveguide (11) functioning as a resonator group consisting of a plurality of resonators (11a to 11e) that are electromagnetically coupled to each other. The post-wall waveguide (11) has a broad wall (first broad wall 112) that is provided with openings (112a to 112e) which allow opening of at least one resonator (11a to 11e) belonging to the resonator group. These openings (112a to 112e) are used to adjust a center frequency of a pass band of the filter (1).
