A vertical coupling structure for non-adjacent resonators is provided. The vertical coupling structure has a first resonator and a second resonator. At least one side of the first resonator is formed as a first bent extension structure, and the first bent extension structure includes a slot. The second resonator is not adjacent to the first resonator, and the side of the second resonator opposite to the first bent extension structure of the first resonator further includes a slot, such that the two sides are electrically connected.
