PROBLEM TO BE SOLVED: To make compact and lightweight radio equipment provided with an array antenna device. SOLUTION: The array antenna device is provided with a plurality of antenna elements each including a radiation element A0 to which a radio signal is fed and a plurality of non-excited elements A1-A6 each of which are provided away from the radiation element just for a predetermined interval and to which the radio signal is not fed, and a variable reactance element 25 connected to the non-excited elements A1-A6. A reactance value of the variable reactance element 25 is changed to change an orientation characteristic of the array antenna device. The plurality of antenna elements are formed to be buried within a dielectric 50, and the array antenna device is installed in a mobile telephone set 40. COPYRIGHT: (C)2004,JPO&NCIPI
