DIELECTRIC FILTER
Document Type and Number:
WIPO Patent Application WO/2023/079903
Kind Code:
A1
Abstract:
This dielectric filter (100) comprises a main body (110) having a cuboid shape, and shields (121-126) disposed on side surfaces of the main body (110). The main body (110) includes a plurality of resonator units (131-135) that are arranged in a first direction and crimped. Each of the plurality of resonator units (131-135) includes a dielectric (170) having a cuboid shape, and resonators (141-145) extending in a second direction orthogonal to the first direction in the dielectric (170). The resonators (141-145) are formed by a plurality of plate-shaped conductors (1401, 1402) extending in the second direction. The main surfaces of adjacent conductors (1401, 1402) in the plurality of conductors face each other in the first direction.
