Abstract
Provided is a mobile tri-band antenna system having low profile. The antenna system includes a tri-band feeding unit for dividing a satellite broadcasting signal by a signal channel in an azimuth angle and an elevation angle, and transmitting/receiving the satellite communication signal through distinguishing the satellite communication signal; a beam shaping unit for dividing the satellite broadcasting signals into a first channel signal and a second channel signal, combined power thereof through channel switching; an antenna controlling unit for driving an antenna system in an azimuth and elevation angle to direct the satellite according to the power combined second channel signal from the beam shaping unit; a first triplexer unit for outputting the power combined first channel signal to a rotary joint unit; a second triplexer unit for converting the first channel signal inputted to a downlink frequency and providing the converted first channel signal to the indoor apparatus.
