Abstract: PURPOSE: To reduce height without lowering a Q value, to dispense with substrate packaging and to reduce the number of parts and that of assembling processes. CONSTITUTION: Two dielectric resonators are constituted by stacking two dielectric blocks on a dielectric base material 11, respectively and covering the whole with a metallic case 10'. One groove 5 is formed by extending in one direction on a side confronting with a packaging face P whose one face is covered with a conductor part in the dielectric base material 11, and the conductor part 6 covering the confronting face R side of two projecting parts 22 and the conductor part of the packaging face P are short-circuited by the conductor part covering one end face in one direction of each projecting part 22 in an alternate direction. The conductor part 6 of each dielectric block 1 covering both confronting faces extending in the longitudinal direction is short-circuited by the conductor part 6 covering one end face in the longitudinal direction, however, the conductor part on one end face is placed on the confronting face in a direction to align with the conductor part on one end face of each projecting part 22.

Abstract: PURPOSE:To obtain a resonator and a dielectric filter with small size and light weight. CONSTITUTION:Dielectric boards 11, 12 are overlapped with each other via a conductive film 13. Conductor films 14, 15 are applied to an upper side of the dielectric board 11 and a lower side of the dielectric board 12. A conductor film 16 is applied to one end of the dielectric boards 11, 12 and a short-circuit end is adopted for its one-end. Then an open end is adopted for other-end of the dielectric boards 11, 12. A recessed part 31 extended in the lengthwise direction of the dielectric boards 11, 12 is provided to the open-end. A conductive film 32 connecting electrically to the conductor film 13 is formed to the recessed part 31. Through the constitution above, the static capacitance around the open-end is increased, as the result, the size of the resonator in a prescribed direction is reduced without changing the resonance frequency. Then the size and the weight of the dielectric filter itself are made small and light by using plural number of the resonators to form the dielectric filter.

Abstract: PROBLEM TO BE SOLVED: To perform the adjustment of a pass frequency band, to improve the yield and to reduce the cost by partly eliminating and reducing the length of the input/output electrodes which are formed in the height direction of a dielectric block and with length equal to its height. SOLUTION: A dielectric filter has an external conductor 11 which is formed by covering the outer surface of a rectangular parallelepiped dielectric block 10 with a conductive film. A non-through holes 12 are formed in the lengthwise direction and from the rear face toward the front face of the block 10. The inner surfaces of every hole 12 is covered with a conductive film and forms a center conductor 13. The conductors 13 are electrically connected to the conductor 11 on the rear face of the block 10. The conductor 11 is partly deleted, so that the input/output electrodes 14 are formed on both side faces 20 and 21 of the block 10 opposite to each other. The length of every electrode 14 is partly eliminated, so that length of the electrode 14 is reduced in the height direction of the block 10. As a result, a pass frequency band shifts to the high frequency side and the attenuation is increased at the frequency bands existing before and after the pass frequency band.
