The purpose of this paper is to improve a feedback-type adaptive array antenna with feedback information quantized by one bit which is presented recently by an author of this paper. The improvement is made by using adaptive instead of constant update size of adaptive antenna weights control. The computer simulation results show that the performance of this system is improved to be almost equivalent to the performance of a system without quantization of the feedback information for wide range of fading speed. The results include the effect of spacing distance between antennas, control delay time and the maximum Doppler frequency under flat fading and frequency-selective fading.
