摘要： A stripline filter includes a ground electrode, input and output electrodes, top-surface resonant lines, side-surface resonant lines, side-surface line portions, connection electrode portions, and top-surface line portions. The ground electrode is provided on the bottom side of a dielectric substrate. The input and output electrodes are provided on the bottom surface of the substrate so as to be separate from the ground electrode. The top-surface resonant lines are provided on the top surface of the substrate. The side-surface line portions, the connection electrode portions, and the top-surface line portions connect two of the top-surface resonant lines to the input and output electrodes. The line width of the two top-surface resonant lines is smaller than the line width of the remainder of the top-surface resonant lines.

摘要： The element size of a stripline filter that achieves a high efficiency percentage with optional stable filter characteristics, is reduced. A stripline filter includes substantially L-shaped top surface resonant lines. The top surface resonant lines include connection electrode parts, first line parts, and second line parts. The connection electrode parts are formed so as to have a width greater than line widths of side surface resonant lines. Each line part faces an edge of a corner portion of a central top surface resonant line at an interval. An edge of each first line part on an edge side of a dielectric substrate, other than a connection portion with the connection electrode part, faces an edge of the dielectric substrate at an interval.

摘要： A filter element includes a flat dielectric substrate, a ground electrode on a back main surface of the dielectric substrate, resonant lines each having a shorting end in the vicinity of a border between a side of the dielectric substrate and the ground electrode and extending from the side to a front main surface of the dielectric substrate. The resonant lines and the ground electrode constitute strip-line resonators. In any of the strip-line resonators, the line width of the resonant-line side portion is different from the line width of the resonant-line main-surface portion.

摘要： A method of adjusting characteristics of a dielectric filter having integral electromagnetic shielding, the dielectric filter comprises a dielectric body having an outer surface including first and second end surfaces and side surfaces extending between the first and second end surfaces; an external conductor disposed on the outer surface of the dielectric body and providing integral electromagnetic shielding of the dielectric filter; at least one hole extending through the dielectric body between the first and second end surfaces; a respective pair of internal conductors provided in the at least one hole and conductively connected to the external conductor at respective ends of the hole, a respective non-conductive portion in the hole being spaced from both ends and thereby separating the pair of internal conductors and defining a respective capacitance between the pair of internal conductors; and signal input and output electrodes provided on the outer surface of the dielectric body and electrically isolated from the external conductor. According to the method, a portion of the dielectric material is removed, for example by grinding, to form the respective non-conductive portion in the hole. The hole may have a changing diameter along its length, due to a hollow formed in one end surface, the non-conductive portion being adjacent to the hollow; or due to a narrowed throttle portion formed at or near the end surface, the non-conductive portion being formed on the throttle portion. Alternatively, the hole may have a substantially constant cross-section, and the non-conductive portion may be substantially flush with the inner surface of the hole. The dielectric body may be regular in shape or may have a side surface with portions spaced from the resonator hole by different respective distances.

摘要： A dielectric filter is provided which permits one to obtain desired external coupling easily without lowering Qo of resonators. The filter comprises a dielectric block having an open end surface and a shorted end surface and provided with resonator holes. Excitation holes are formed in the block outside the resonator holes, respectively. Input/output electrodes are formed on the open end-surface. The electrodes are electrically connected with conductors formed inside the excitation holes but isolated from an outer conductor. The conductors inside the excitation holes are electrically connected with the outer conductor on the shorted end surface. The excitation holes are electromagnetically coupled to the respective adjacent resonator holes, thus providing external coupling.

摘要： Resonance holes whose inner surfaces are covered with an inner conductor (or other inner conductor structures) are formed in a dielectric block such that the resonance holes extend between two opposing end faces. The outer surface of the dielectric block is covered with an outer conductor. Input/output electrodes are formed out of part of the outer conductor at predetermined locations on the surface of the dielectric block. A slot is formed near one end face of the dielectric block so that the inner conductors are separated by the slot into isolated parts. By means of the slot, an electrically open end of each resonator is formed at a location spaced inward from the physical end face. Thus it is possible to produce a low-cost high-performance dielectric filter in which an electrically open end is formed with high accuracy at a location spaced inward from the physical end face of a dielectric block.

摘要： In a dielectric resonator, through holes are formed between opposing two surfaces of a dielectric block, an outer conductor is provided on an outer peripheral surface of the dielectric block, and a plurality of inner conductors are formed on the inner surfaces of the through holes, isolated by non-conducting portions where the inner conductor is not provided. Near the open end of the inner conductor of the resonator hole, a non-conducting portion is formed by partially removing the inner conductor in the axial direction, at a position opposing to an adjacent through hole, or a position near the outer conductor, so as to increase odd mode or even mode characteristic impedance near the open end, whereby inductive coupling is adjustable.

摘要： To reduce the number of components and enable the mounting work of a filter unit onto a printed substrate without using a metal case, a filter unit of three-state structure with resonators is constructed in which an electrode is formed on an inner peripheral surface of each through-hole and an outer peripheral surface of a dielectric member except for one end face, and connector terminals each composed of a pin and an insert member are inserted into opening portion of the end face of the through-holes to form a dielectric bandpass filter. An enlarged insert portion is formed in the opening portion of each through-hole so as to form a stepped portion between the insert portion and a non-insert portion. The insert member has the same configuration as that of the insert portion and is inserted and fitted in the insert portion without projecting from the end face. At the same time, the movement of the insert member toward the non-insert portion is restricted by the stepped portion. The connector terminals are mounted in a stationary manner in a predetermined position within the through-holes.
