摘要： A dielectric resonator is arranged such that an upper electrode 4a and a lower electrode 4b are disposed on both surfaces of a dielectric substrate 1 that has an interior metallized layer inside thereof, which is formed with a resonance aperture area 3. A dielectric filter is produced by arranging a plurality of rows of the dielectric resonators, and using a multilayer-type waveguide 6 formed by lines of via conductors for signal input and output. This dielectric filter allows the accuracy for designing resonant frequencies to be greatly improved and the production process to be simplified.

摘要： A dielectric filter includes a case, a substrate having microstrip lines formed thereon, and a dielectric plate having non-electrode parts serving as dielectric resonators. The case includes a supporting part for supporting the lower surface of the dielectric plate and includes a side wall surrounding the side faces of the dielectric plate wherein the supporting part and the side wall are formed in an integral fashion. The substrate is bonded to the case and the dielectric plate is mounted on the supporting part of the case. A metal cover is then placed on the case such that the opening of the case is closed with the cover. In the dielectric filter constructed in the above-described manner, warping of the case for supporting the dielectric plate is suppressed and thus the stress exerted on the dielectric plate is reduced. As a result, the dielectric plate is prevented from being separated from the case and also prevented from having a crack. The above-described structure also allows the dielectric filter to be formed into a small size. The invention also provides a duplexer and a communication device using such a dielectric filter.

A TE010-mode resonator is constituted by two circular openings which oppose each other and which are formed in the electrode films. Two opposing slots formed in the electrode films constitute a planar dielectric transmission line (PDTL). The PDTL is connected to the TE010-mode resonator. An excitation section is formed by extending two portions of each electrode film on two side of each slot into each opening.
