Abstract
An array antenna device according to an embodiment has a first sub-array antenna and a second sub-array antenna, a driver, and a feeder. The first sub-array antenna and the second sub-array antenna have a plurality of radiating elements arranged in a reference plane. The driver, by changing the orientation of at least one of the first sub-array antenna and the second sub-array antenna, causes the normal lines of the reference planes of the first sub-array antenna and the second sub-array antenna to intersect. The feeder performs in-phase power feed to the first sub-array antenna and the second sub-array antenna, and performs opposite-phase power feed to the first sub-array antenna and the second sub-array antenna.
