ANTENNA DIRECTIVITY CONTROL SYSTEM AND WIRELESS DEVICE PROVIDED WITH SAME

摘要

Provided is an antenna directivity control system, comprising: an antenna having a plurality of antenna elements having different feed points; and a control means for controlling the weights of the antenna elements. The plurality of antenna elements each comprise: a feed element which is connected to the feed point; and a radiating element which is fed by being electromagnetically coupled to the feed element and functions as a radiating conductor. The control means adjusts the amplitude of signals at each of the feed points and controls the directivity of the antenna.
