    摘要： In a dielectric filter in which electrodes (1, 2) are formed on both principal planes of a dielectric plate (3) while pairs of electrode non-formed portions (4a, b, c) having substantially the same shape are defined in the electrodes (1, 2) in opposing relation, areas positioned between the pairs of opposing electrode non-formed portions (4a, b, c) serve as resonance areas (14a, b, c), coupling members are provided to be coupled with the resonance areas (14a, b, c), and a cavity is provided to define a space surrounding the resonance areas (14a, b, c) and the coupling members, a signal is prevented from propagating in the parallel plate mode through a waveguide path formed between electrodes (11, 12) formed on both principal planes of the base plate (6) serving as part of a cavity. Electrodes are formed on both principal planes of a dielectric plate (3) with pairs of electrode non-formed portions (4a, 4b, 4c, etc.) defined in the electrodes in opposing relation so that areas positioned between the electrode non-formed portions serve as resonance areas. Microstrip lines (9, 10) are provided on an upper surface of a base plate (6), and an electrode (11) is formed in spaced relation from the microstrip lines (9, 10) by a predetermined distance. Through holes (13) for making electrical conduction between the electrodes formed on both principal planes of the base plate (6) are bored in the base plate in array.

    摘要： A dielectric filter is formed by constituting electrode non-formation parts (4a,4b,5a,5b) opposed as inserting both main surfaces of a dielectric plate (3) as dielectric resonator (45a,45b), as well as by providing two coupling members (10,11) coupled to said dielectric resonator, and a large attenuation quantity required for a certain frequency in a blocking area is secured by generating an attenuation pole in a predetermined frequency area. A dielectric resonator is constituted by providing an electrode (1) on an upper surface of a dielectric plate (3) as a portion thereof being an electrode non-formation part (4a,4b), providing an electrode (2) on a lower surface of the dielectric plate (3) as a portion opposite to the electrode non-formation part (4a,4b) being an electrode non-formation part (5a,5b), and nearly placing probes (6,7) as coupling members (10,11), as well as placing both probes (6,7) in non-parallel.

    摘要： There is provided a dielectric resonator (1) which can suppress a spurious output acting as unnecessary resonance and can prevent the out-of-band characteristics of a filter from being degraded. Electrodes (2a,2b) having circular openings (2c,2d) are formed on a dielectric substrate (2), and the dielectric substrate (2) is arranged between upper and lower conductive cases (3,4). A resonance region is used as a portion between the openings (2c,2d) of the dielectric substrate (2), and columnar members (7,8) consisting of a wave absorber are arranged between the upper and lower conductive cases (3,4).

    摘要： A dielectric substrate (2) is provided on its both main surfaces with conductors (2a, 2b) each having two circular openings such that the openings on both main surfaces oppose each other. On one conductor (2a) of the dielectric substrate (2), an insulating layer (2c) is formed. On the insulating layer (2c), an input electrode (4a) and an output electrode (4b) are formed. Electrically conductive plates (3a, 3b) are disposed and secured such that they sandwich the dielectric substrate (2) with gaps therebetween.

Electrodes (2a,2b) having circular openings (2c,2d) are formed on a dielectric substrate (2), and the dielectric substrate (2) is arranged between upper and lower conductive cases (3,4). A resonance region is used as a portion between the openings (2c,2d) of the dielectric substrate (2), and columnar members (7,8) consisting of a wave absorber are arranged between the upper and lower conductive cases (3,4).
