ANTENNA RF MODULE, RF MODULE ASSEMBLY, AND ANTENNA DEVICE INCLUDING SAME

Abstract

The present invention relates to an antenna RF module, an RF module assembly, and an antenna device including same. Particularly, the present invention comprises an RF filter which has at least four outer side surfaces, a radiation element module which is disposed on one surface of the outer side surfaces of the RF filter, an amplifier substrate which is disposed on another surface of the outer side surfaces of the RF filter and on which an analogue amplification element is mounted, and a reflector which is disposed between the RF filter and the radiation element module to ground (GND) the radiation element module and also mediate the outwardly dissipating heat generated by the RF filter, wherein socket pins are coupled to a main board disposed at an antenna housing in a unit of a module. Accordingly, a radome which hinders heat dissipation toward the front of the antenna is not needed and heat generated by heating elements of the antenna device is spatially separated so that the distributed heat dissipation toward the front and rear of the antenna device is possible, thereby remarkably improving heat dissipation performance.
