Antenna for satellite communication

An antenna for satellite communication comprises:

• a signal transmitting and receiving unit for receiving or transmitting a signal from/to a satellite;
• a driving unit coupled to the signal transmitting and receiving unit for rotating the signal transmitting and receiving unit so as to enable the signal transmitting and receiving unit to track the satellite;
• a first post on which the signal transmitting and receiving unit is mounted through the driving unit, the first post being formed of a hollow tube;
• a second post coupled to the first post, the second post being formed of a hollow tube, and the first post being inclined with respect to the second post at a predetermined angle;
• and
• an anti-vibration unit disposed inside the second post for elastically supporting the signal transmitting and receiving unit and the driving unit,
• wherein the anti-vibration unit comprises:
• a damper shaft provided inside the second post along a longitudinal direction of the second post, a plurality of damper springs wound around an outer surface of the damper shaft along a longitudinal direction of the damper shaft, and an elastic member disposed between two neighboring windings of the damper springs,
• wherein the first post is coupled to an upper portion of the damper shaft of the anti-vibration unit, and
• wherein the elastic member has a same form as that of the damper springs so as to surface-to-surface contact with the two neighboring windings of the damper springs.
