DIELECTRIC RESONATOR, AND DIELECTRIC FILTER AND MULTIPLEXER USING SAME

WIPO Patent Application WO/2022/209457

A1

A filter device (100) comprises: a laminated body (110); plate electrodes (130, 135); a plurality of resonators (140); shield conductors (121, 122); and a connection conductor (150). The laminated body comprises a plurality of dielectric layers. The plate electrodes are disposed apart from each other in the laminating direction, inside the laminated body. The plurality of resonators are disposed between the plate electrodes and extend in a first direction orthogonal to the laminating direction. The shield conductors are respectively disposed on side surfaces (115, 116) of the laminated body, and are connected to the plate electrodes. The connection conductor connects the resonators to the plate electrodes (130, 135). The resonators are disposed to be aligned in a second direction, inside the laminated body. Respective first ends of the resonators are connected to the shield conductor (121), and respective second ends thereof are spaced apart from the shield conductor (122).
