構成とした誘電体共振器を利用してフィルタを構成した
ものが誘電体フィルタである。The dielectric 12 is electromagnetically sealed by a metal cavity 11 and held on a support 13.
Here, the coupling loop 14 is inserted into the cavity 11 from one end of the cavity 11 and electromagnetically coupled to the dielectric 12, so that the entire resonator can be a resonator (dielectric resonator). At this time, the frequency adjustment member 401 is used to adjust the resonance frequency of the dielectric resonator. That is, the resonance frequency is adjusted by changing the distance between the plate portion 4011 of the frequency adjusting member 401 and the dielectric 12. For example, when using TE 01 Teruta mode, the closer the distance between the plate portion 4011 and the dielectric 12, it is possible to increase the resonance frequency. A dielectric filter is one in which a filter is constructed using the dielectric resonator having such a configuration.

Since the resonance frequency is almost determined by the coupling degree according to 4, the frequency adjusting member 401 is used for final fine adjustment of the resonance frequency in manufacturing. The larger the plate portion 4011 is, the larger the frequency variable range is, and the smaller the plate portion 4011 is, the finer fine adjustment can be performed.

共振周波数を得ることが困難であった。However, the above structure has the following problems because the plate portion 4011 has only one size. That is, when the resonance frequency of the resonator is accurately adjusted, the size of the plate portion 4011 may be reduced, but in this case, the frequency adjustment range is narrowed, so that the effective inner size of the cavity 11 and the dielectric It was necessary to have the shape and permittivity of 12 and the degree of coupling by coupling loop 14 determined. Further, if the effective inner size of the cavity 11, the shape and permittivity of the dielectric body 12, and the coupling degree by the coupling loop 14 are to be allowed, a large frequency variable range is required, and thus the plate portion 4011 is relatively large. Although it will have an area, in this case,
Even when the distance between the plate portion 4011 and the dielectric 12 slightly changes, the resonance frequency changes abruptly, so that it is difficult to obtain an accurate resonance frequency.
