12. An antenna apparatus comprising:
a main board, at least one digital element being mounted on a front surface or rear surface of the main board;
a casing-shaped rear housing formed to have an installation space in which the main board is installed, the installation space being open at the front side;
a front housing arranged to close the installation space in the rear housing and separate the installation space in the rear housing and an outside space; and
a plurality of antenna RF modules arranged in front of the front housing and connected to the main board through an electrical signal line,
wherein each of the plurality of antenna RF modules comprises:
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; and
an amplification unit module arranged between the main body and the RF filter, at least one analog amplification element being built into the amplification unit module,
wherein the amplification unit module comprises:
an amplification unit body having a board seating space that is open at one side or the other side in a width direction;
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.
