Abstract
According to one embodiment, an antenna device includes a first antenna part, a first power divider, and a first control circuit. The first antenna part includes first antenna elements, first phase shifters for left-handed circular polarized wave, and first phase shifters for right-handed circular polarized wave. The plurality of first antenna elements performs a first transmitting operation of transmitting a transmitting-left-handed circularly polarized wave, and a second transmitting operation of transmitting a transmitting-right-handed circularly polarized wave. The first power divider is couplable with the plurality of first phase shifters for left-handed circular polarized wave and the plurality of first phase shifters for right-handed circular polarized wave. The first control circuit controls phase shift amounts of the plurality of first phase shifters for left-handed circular polarized wave and controls phase shift amounts of the plurality of first phase shifters for right-handed circular polarized wave.
