Abstract
An antenna directivity control system includes an antenna including a plurality of antenna elements, feeding points for the plurality of antenna elements being mutually different; and a controller for controlling weight for each of the plurality of antenna elements, wherein each of the plurality of antenna elements includes a feed element connected to the feed point, and a radiating element that functions, upon power being fed by establishing electromagnetic field coupling with the feed element, as a radiating conductor, and wherein the controller controls a directivity of the antenna by adjusting an amplitude of a signal at each of the feeding points.
