Claim 39:
40. The filter comprising the high-Q triple-mode dielectric resonance structure as claimed in claim 39, wherein, the dielectric resonance block has a single dielectric constant or a composite dielectric constant; the dielectric resonance block with the composite dielectric constant is made of at least two materials with different dielectric constants; materials with different dielectric constants are combined by up and down, or left and right, or asymmetric or nested manners; when materials with different dielectric constants are nested in the dielectric resonance block, one layer of or a plurality of layers of materials with different dielectric constants are nested in the dielectric resonance block; the dielectric resonance block with the composite dielectric constant needs to meet a change variation rules of Q-value conversion points; when side cutting coupling is performed among triple modes of the dielectric resonance block, in order to maintain a required frequency, corresponding side lengths of two surfaces adjacent to cut sides are adjusted in parallel; the dielectric resonance block is made of ceramic or dielectric materials; and a surface of the dielectric resonance block is added with dielectric sheets with different thicknesses and different dielectric constants.
