1. An antenna apparatus comprising:
one or more antenna placement units in which at least one radiation element is disposed on a front surface of the antenna placement unit;
a front heat dissipation housing comprising a heat dissipation unit integrally formed between adjacent antenna placement units, among the one or more antenna placement units, exposed to an air, and configured to forward transfer heat that is generated from a back of the heat dissipation unit; and
a rear heat dissipation housing coupled with the front heat dissipation housing and having a main board on which a filter for filtering an RF signal and an RF element are mounted provided within the rear heat dissipation housing,
wherein heat that is generated from the filter is transferred to a front surface of the front heat dissipation housing through a contact with a back surface of the front heat dissipation housing by using the filter itself as a heat transfer medium,
wherein the radiation element comprises:
an antenna patch circuit unit printed and formed on a printed circuit board for a radiation element that is disposed in the antenna placement unit; and
a director for radiation made of a conductive metal material and electrically connected to the antenna patch circuit unit.
