Title:
DIELECTRIC WAVEGUIDE RESONATOR AND DIELECTRIC WAVEGUIDE FILTER
Document Type and Number:
WIPO Patent Application WO/2021/117355
Kind Code:
A1
Abstract:
This dielectric waveguide filter (101) is provided with: a dielectric plate (1) having a first main surface (MS1) and a second main surface (MS2) facing each other, and side surfaces (SS) connecting the outer edges of the first main surface (MS1) and the outer edges of the second main surface (MS2); a first surface conductor (21) formed on the first main surface (MS1); a second surface conductor (22) formed on the second main surface (MS2); side surface conductor films (8A-8D) formed in the interior of the dielectric plate (1) and connecting the first surface conductor (21) and the second surface conductor (22); and internal conductors (7A-7D) that extend perpendicular to the first main surface (MS1) and that are not electrically connected to the first surface conductor (21) or to the second surface conductor (22). A plurality of dielectric waveguide resonance spaces are formed in the space surrounded by the first surface conductor (21), the second surface conductor (22), and the side surface conductor films (8A-8D).
