Description of the Invention (1) (Background of the Invention) The present invention relates to a double-type dielectric using three dielectric modes with one dielectric block And a dielectric filter using the dielectric resonator. In the past, in order to realize a low-loss and compact filter, a dielectric filter without a dielectric resonator having a high load Q has been used. In particular, a filter that emphasizes low-loss characteristics is a dielectric filter using a T E 0 i 5 mode dielectric resonator with minimal conductor loss in principle. On the other hand, in order to miniaturize the dielectric filter, a dielectric resonator using a dielectric material having a higher specific permittivity and a higher no-load Q is used. Press' to use majority T E. : 5 mode dielectric resonators, such as dielectric filters used in wireless communication such as microwave bands, that is, one resonator is required for one resonance, and there must be a space for combining between the resonators As a result, most resonators and the space between the resonators will occupy a large volume and weight. As a result, the dielectric filter is compact. It is difficult to reduce weight, so although a band pass filter made of a relatively small dielectric resonator is used, it still has a complex structure that cannot be avoided and becomes a large problem. Therefore, in order to make full use of the advantages of using a dielectric resonator, as a very small and simple band-pass filter, a proposal is made to use a dielectric resonator that can make multiple modes of resonance. Electric quality filter. For example, Japanese Patent Application Laid-Open No. 7-5 8 5 16 proposes to reduce the number of resonance cycles of the two resonance modes to be different from each other so as to miniaturize a band-pass filter having complex homology band characteristics. It is revealed that the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). -------- Order --------- (Please read the precautions on the back before filling (This page) -4- Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs's Consumer Cooperatives 477089 A7 _ ____B7 V. Description of the Invention (2) There is a regression combination of the two resonance modes for TE 1 ϋ 1, τ E 1 i 5 mode. Furthermore, Japanese Unexamined Patent Publication No. 1 1 1 4 5 7 0 4 proposes that the dielectric blocks in the shape of a substantially rectangular parallelepiped, on the planes of the rectangular coordinate system (XY plane, Y-Z plane, X-Z plane). ) The multi-mode dielectric resonators of TMQ i 5 mode and TEQ i δ mode obtained from the parallel plane respectively. However, the band-pass filter of the multi-stage resonator is required, even if the above characteristics are used In combination with the retreat of the two resonance modes described in Kaiping Publication No. 7-5 8 5 16, it is still inevitable to increase the volume occupied by the dielectric resonator. Furthermore, although a triple mode dielectric resonator is described in JP-A-H11-114-5704, because orthogonal space TE is used. : 5 modes and τ Ε. The combination of i 5 modes requires the thickness of the dielectric resonator to be matched to the number of resonance cycles. Therefore, the manufacturing process becomes complicated (the main point of the present invention). The purpose of the present invention is to solve the above-mentioned past problems. The problem that the example has is to provide a dielectric resonator that can be very small and simple, and a dielectric filter using such a dielectric resonator, although it is possible to achieve triple mode resonance.
