PURPOSE: A satellite-antenna apparatus is provided to achieve improved receiving performance of the apparatus by adjusting the azimuth angle of a moving body with respect to an artificial satellite. CONSTITUTION: A satellite-antenna apparatus(MA) comprises at least n-numbers(wherein n is an integer larger than 3) of array antennas(2a,2b,2c); and a plurality of antenna elements arranged in the array antennas. The array antennas form an n-squared shape, and are arranged to have different azimuth angles with respect to an artificial satellite. The signal received at one of the array antennas is processed in accordance with the azimuth angle of a moving body with respect to the artificial satellite, and transmitted to the set top box of the television of the moving body.
