摘要： A dielectric resonator (38) with a dielectric block (30). The block has a plurality of resonance apertures (32) and coupling-prevention aperture (34) between the adjacent resonance apertures within the block. The block is entirely coated with a conductive film except a limited portion around the one end of the resonance apertures.

CPC分类号： H01P1/20336
摘要： The invention relates to a dielectric filter with attenuation poles. A first dielectric block or blocks (1) have a cut out portion and the cut out space is filled with a second dielectric block (6). A bypass pattern (7) is formed on the second dielectric block (6) and is capacitively coupled with two resonance elements formed on the first dielectric blocks (1). The dielectric filter is compact, and the position and intensity of attenuation poles can be freely designed and easily adjusted.

摘要： A dielectric resonator block has at least three resonators and coupling device for coupling the adjacent resonators. A reactance element is added in parallel to the coupling device to provide an attenuation pole. A capacitor block of a dielectric material is provided which has through-holes to form hole electrodes and a surface electrode so that two coupling capacitances are provided. One of the two coupling capacitances serves as the reactance element. One of the hole electrodes of the capacitor block is connected with an external connector, and the other hole electrodes are connected with the resonators.
