Abstract
An array antenna apparatus which has an away antenna formed by a plurality of antenna elements, and subjects received signals, which are received by the antenna elements, to weighting using array weights of complex numbers. The array antenna apparatus includes a delay device for delaying a signal; a weighting device for separating ea of the received sirs into first and second received signals, delaying any one of the first and second received signals by using the delay device, so as to weight the first and second received signals at different timings; and a first adding device for adding the weighted first and second received signals to each other. The weighting device weights any one of the first and second received signals by using the real part of the relevant array weight, and weights the other received signal by using the imaginary part of the array weight.
