CAPACITIVE COUPLING STRUCTURE FOR DIELECTRIC WAVEGUIDE FILTER AND DIELECTRIC WAVEGUIDE FILTER

WIPO Patent Application WO/2020/252946

A1

Disclosed are a capacitive coupling structure for a dielectric waveguide filter, and a dielectric waveguide filter. The capacitive coupling structure comprises a through-hole provided between two adjacent dielectric resonators in a dielectric body, and a first adjustment recess and a second adjustment recess provided along the circumference of the through-hole. The first adjustment recess is non-closed, and the second adjustment recess is closed. Both the first adjustment recess and the second adjustment recess pass through a conductive layer of the dielectric body. A first plane on which the first adjustment recess is located is opposite and spaced apart from a second plane on which the second adjustment recess is located. The distance between the first plane and the second plane is less than the thickness of the dielectric body. The capacitive coupling structure is easy to machine, such that difficulties in solving production problems are reduced, and production quality is ensured. Thus, difficulties in production of a dielectric waveguide filter employing the capacitive coupling structure are reduced, and the dielectric waveguide filter has high quality, and is suitable for mass production.
