Abstract
According to the present invention, there is provided an adaptive array antenna including a plurality of antenna elements for receiving radio waves transmitted via multi-carrier waves, weighting means for weighting received signals received by the plurality of antenna elements with weight amounts for the respective antenna elements, adding means for adding up weighted signals by the weighting means, extracting means for extracting particular carrier components from the received signals received by the plurality of antenna elements, and weight setting means for setting the weight amounts for the respective antenna elements to the weighting means on the basis of the particular carrier components extracted by the extracting means.
