Abstract
An array antenna includes a group of antenna elements and a switching section. The group of antenna elements has a configuration in which a plurality of antenna elements is arranged. The switching section has a plurality of switch elements capable of individually switching the feeding points of the antenna elements included in the group of antenna elements. By switching of the switch elements, the group of antenna elements is converted into an antenna for MIMO communication to transmit and receive a plurality of signals in parallel, or into a directional array antenna to control the directivity towards the direction at which the signals arrive.
