A filter includes a filter frame and at least two resonators. A receiving space is formed in the filter frame. The at least two resonators are disposed in the receiving space and distributed along a signal transmission path. Adjacent resonators on the signal transmission path are coupled. Each resonator includes a body part and a bending part. One end of the body part is grounded. The bending part includes a head bending part and an end bending part, the head bending part being connected to the end bending part to form a resonator structure circulating in a counterclockwise or clockwise direction.

Filter

A single-layer cross-coupling filter includes a cavity in which a receiving space is formed; an integrally formed resonant structure installed in the receiving space; and at least one partition wall. The resonant structure includes at least two rows of resonant units distributed along a signal transmission path. The at least two rows of resonant units are located in a same plane of the receiving space, and each row of the resonant units includes a plurality of resonators. The resonators on a same row are coupled and connected to form signal transmission, and at least two adjacent resonators in different rows are coupled and connected to realize cross-coupling.
