Abstract
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.
