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.
