Abstract: The present invention relates to a cavity filter. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion is divided into a first side terminal contacted with the electrode pad and a second side terminal connected to the RF signal connecting portion, absorbs the assembly tolerance existing in a terminal insertion port, in which the terminal portion is provided, through an elastic member provided between the first side terminal and the second side terminal, and prevents disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.

Abstract: The present disclosure relates to an antenna RF module, an RF module assembly including the antenna RF modules, and an antenna apparatus including the RF module assembly. Particularly, the antenna RF module includes an RF module, a radiation element module arranged on a first side of the RF filter, and an amplification unit board arranged on a second side of the RF filter, an analog amplification element being mounted on the amplification unit board. A plurality of antenna RF modules constitute the RF module assembly, and the RF module assembly and an antenna housing constitute the antenna apparatus. Accordingly, a radome that interrupts dissipation of heat to in front of an antenna is unnecessary, and heat generated from heat generating elements of the antenna apparatus is spatially separated. Thus, it is possible that the heat is dissipated in a distributed manner toward the front and rear directions of the antenna apparatus. The effect of greatly improving performance in heat dissipation can be achieved.
