The present invention relates to a cavity filter assembly, and more particularly, to a cavity filter assembly comprising: a filter body having a cavity as a predetermined space therein; and at least one resonance rod which has, on the front end surface thereof, a carved portion as a protruding surface protruding from the bottom surface of the filter body to the cavity side so as to be parallel to the bottom surface of the filter body in the cavity, so as to tune the frequency in the cavity, and which has, formed therein, a tuning correction hole penetrating through the carved portion, so as to correct the frequency in the cavity. The resonant rod can tune the frequency in the cavity by carving the outer side surface of the carving part on the outer side of the filter body, and the tuned frequency can be corrected through the tuning correction hole, so that the antenna has the advantages of reducing the total weight of antenna equipment, reducing the cost of accessories and improving the productivity of produc
