Abstract
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.
