Proposed are an antenna RF module and an antenna apparatus including the antenna RF modules. The antenna RF module includes an amplification unit module which is arranged between a main board and an RF filter and into which at least one analog amplification element is built. The amplification unit module includes an amplification unit body, an amplification unit board seated inside the amplification unit body, a front end portion of an edge of the amplification unit board being connected to the RF filter for signal transmission and a rear end portion of the edge thereof being connected to the main board for signal transmission, an amplification unit cover provided in such a manner as to cover the amplification unit board, and a vapor chamber positioned between the amplification unit body and the amplification unit board or between the amplification unit cover and the amplification unit board and serving as a medium for transferring heat generated from analog amplification elements mounted on the amplification unit board.

RF module for antenna and antenna apparatus comprising same

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.

Proposed are an antenna RF module and an antenna apparatus including the antenna RF modules. The antenna RF module includes an RF filter arranged on a front surface of a main board, a radiation element module arranged on a front surface of the RF filter, at least one reflector grill pin arranged between the RF filter and the radiation element module and grounding (GND) the radiation element module, outside air being introduced from in front of the RF filter to in back of the RF filter or being discharged from in back of the RF filter to in front of the RF filter through the at least one reflector grill pin, and a radome cover combined with the front surface of the RF filter and protecting the radiation element module from the outside. The antenna RF module provides the advantage of greatly improving overall performance in heat dissipation.
