PROBLEM TO BE SOLVED: To facilitate initial position setting of a primary radiator or positional adjustment due to movement of a moving object in an antenna device for moving object communication, while aiming at improvement of a radio wave lens antenna system employing a Luneberg lens complying to a geostationary satellite. SOLUTION: The antenna system has an antenna unit 1 consisting of a Luneberg lens 2 for converging captured radio waves, a reflection plate 3, a primary radiator 4, and a supporting arm 5 for holding the primary radiator 4 on the focusing portion of the lens. A platform 13 is attached on the supporting arm 5, and the attaching portion of the primary radiator 4 is provided on the platform 13. Thus, a plurality of primary radiators 4 can be attached on the same platform 13. COPYRIGHT: (C)2007,JPO&INPIT
