Claim 21:
22. A filter comprising the high-Q triple-mode dielectric resonance structure, comprising a cavity body, a cover plate and an input/output structure, and wherein, the cavity body is internally provided with at least one high-Q triple-mode dielectric resonance structure as claimed in claim 1;
the high-Q triple-mode dielectric resonance structure, a single-mode resonance structure, a two-mode resonance structure and a triple-mode resonance structure are combined in different forms to form filters of different volumes;
coupling between any two resonance cavities formed by an arrangement and combination of the high-Q triple-mode dielectric resonance structure, a single-mode resonance cavity, a two-mode resonance cavity, and a triple-mode resonance cavity is realized through a window size between the any two resonance cavities only under a condition that resonance rods in the two resonance cavities are parallel; the window size is determined according to the coupling quantity;
and the filters have functional characteristics that the filters comprise but are not limited to band pass filters, band stop filters, high pass filters, and low pass filters, and duplexers, multiplexers and combiners formed by the band pass filters, band stop filters, high pass filters, and low pass filters.
