Hybrid antenna system
A hybrid antenna system for providing a communication service or/and a satellite broadcasting receiving service by coarsely tracking a target satellite in a mechanical fashion and finely tracking the target satellite in an electrical fashion is disclosed. The hybrid antenna system includes: a rotatory unit for tracking a satellite direction using a mechanical movement including a rotating motion and an electron beam tracking function and transmitting/receiving a multi-band frequency from a satellite through a free space; a stationary unit for communicating to an external terminal and/or transmitting and receiving a broadcasting signal from/to the external terminal; and a stabilizing unit for connecting the rotatory unit to the stationary unit, and driving and controlling the rotatory unit in mechanical fashion and electrical fashion.
