Antenna apparatus

Abstract

Provided is an antenna device that can facilitate smooth operation of a rotation driving unit due a simplified structure and consequent reduction in weight. To this end, the antenna device according to the present invention comprises: an antenna unit; a support mounting unit that attaches to a support; and a rotation driving unit that attaches to the support mounting unit to allow rotating in the horizontal direction, and when rotated so, that rotates the antenna unit in the horizontal direction, wherein the support mounting unit is provided with an internal gear and the rotation driving unit is provided with an external gear, the external gear engaging with the internal gear when the rotation driving unit is in operation to rotate and move along the inner circumferential surface of the internal gear, thus rotating the rotation driving unit in the horizontal direction.
