An adaptive antenna is disclosed, that comprises a plurality of antenna elements 11, 12, . . . , and 1N with different
directivity,
delay profile measuring units 21, 22, . . . , and 2N for estimating states of received signals of the antenna elements for each of
delay times that have been designated, antenna selecting units 31, 32, . . . , and 3L for selecting a part of the antenna elements for each of the
delay times corresponding to the estimated result, adaptive
signal processing portions 41, 42, . . . , and 4L for determining the received signals of the part of the antenna elements that have been selected and multiplying the received signals to which relevant weights have been determined for each of the
delay time and summing the weighted signals, delaying circuits 52 and 53 for compensating the
time lag, or delay of each of the received signals for each of the delay times, and a combining unit 6 for combining the weighted signals that have been compensated for the delay times.
