Claim 26:
27. The filter comprising the high-Q triple-mode dielectric resonance structure as claimed in claim 22, wherein, when the cavity and the dielectric resonance block have equal sizes in axes X, Y and Z, a degenerate triple-mode is formed, and the degenerate triple-mode is coupled with other single cavities to form a band-pass filter;
when the cavity and the dielectric resonance block have slightly unequal sizes in axes X, Y and Z, an orthogonal-like triple-mode resonance is formed; if the orthogonal-like triple-mode is still coupled with other cavities to form the band-pass filter, sizes are all acceptable; if the orthogonal-like triple-mode is not coupled with other cavities to form the band-pass filter, the sizes are unacceptable;
and when the differences of the sizes of the cavity and the dielectric, resonance block in axes X, Y and Z are greatly different, the degenerate triple-mode or the orthogonal-like triple-mode is not formed, but three modes with different frequencies are formed, thus, the three modes with different frequencies are not coupled with other cavities to form the band-pass filter, and the sizes are not acceptable.
