Stripline laminate dielectric filter with input/output patterns overlapping resonator conductors |
摘要 |
A dielectric filter includes a laminate substrate formed by laminating and bonding a plurality of dielectric sheets, belt-like resonance electrodes formed on predetermined bond surfaces of the dielectric sheets, input/output electrodes formed at predetermined positions of an outer periphery of the laminate substrate and connected to the belt-like resonance electrodes, and earth electrodes formed on the outer periphery of the laminate substrate under a non-connection state with the input/output electrodes. The end portions of the belt-like resonance electrodes extend to both side surfaces of the laminate substrate. One end of each belt-like resonance electrode is connected to the earth electrode formed on one of the side surfaces of the laminate substrate and serves as a short-circuit terminal, and the other end of the belt-like electrode is exposed on an ungrounded portion on the opposite side surface and serves as an open terminal.
