Abstract
The present disclosure relates to a cavity filter assembly and, particularly, comprises: a filter body having a cavity, which is a predetermined space therein; and at least one resonance bar having a front end surface that forms a stamped part, which is a protruding surface protruding from the bottom surface of the filter body toward the cavity so as to be parallel to the bottom surface of the filter body in the cavity, for frequency tuning in the cavity, and having a tuning correction hole that penetrates the stamped part, wherein the resonance bar allows frequency tuning to be performed in the cavity through stamping on the outer surface of the stamped part from the outside of the filter body, and the tuned frequency can be corrected through the tuning correction hole, and thus the advantages of reducing the total weight and component costs of an antenna device and improving product productivity are provided.
