Claim 0:
1. A single-layer cross-coupling filter, comprising:
a cavity in which a receiving space is formed;
a resonant structure installed in the receiving space, and including at least a first and a second rows of resonant units distributed along a signal transmission path, each of the first and the second rows of the resonant units including a left, a middle, and a right resonators, wherein the signal transmission is formed along the first row and the second row, and a cross-coupling is formed between the first row and the second row; and
at least one partition wall arranged between the first and the second rows of the resonant units, wherein a coupling window is formed on the partition wall, the left, the middle, or the right resonator of the first row is respectively connected to the left, the middle, or the right resonator of the second row through the coupling window to form the cross-coupling,
wherein each resonator comprises a body part and a bending part, and the bending part comprises a head bending part and an end bending part, and
wherein the body parts of the middle resonators in the first and the second rows are connected through the coupling window to form inductive cross-coupling.
