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.
A multi-band 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, the multi-band hybrid antenna system comprising:
The multi-band hybrid antenna system as recited in claim 10, wherein the dual band cone shape helix exciter includes a cone shape conductive material having both end points connected to a transmitting terminal and a receiving terminal in order to be operated as a circular polarization of different frequencies.
A multi-band hybrid antenna for providing a communication service and a satellite broadcasting receiving service, the multi-band hybrid antenna comprising:
A method of tracking a satellite in a dual reflector structure hybrid antenna system using a mechanical driving device and an electron beam tracking scheme for coarsely tracking a target satellite in a mechanical fashion and finely tracking a target satellite in an electrical fashion, the method comprising the steps of:
