Abstract
Provided is an antenna device capable of ensuring an installation space for components related to an antenna and eliminating a dead zone of a signal transmitted or received by the antenna by tilting an antenna unit. To this end, the antenna device according to the present invention includes a pole, an antenna unit, a lower link unit configured to couple a lower portion of the antenna unit to the pole so that the lower portion of the antenna unit is rotatable in an upward/downward direction, and a tilt drive unit configured to couple an upper portion of the antenna unit to the pole and tilt the upper portion of the antenna unit by rotating the upper portion of the antenna unit about a rotation center of the lower link unit, in which the tilt drive unit includes a tilt motor, a worm gear configured to be rotated by driving power of the tilt motor, a first tilt arm coupled to the antenna unit, a second tilt arm coupled to the pole, a first worm wheel configured to rotate the first tilt arm by being rotated by a rotation of the worm gear, and a second worm wheel configured to rotate the second tilt arm by being rotated by a rotation of the worm gear.
