Traditionally, the aperture distribution of the sum pattern for the receive array antenna is symmetrical and the aperture distribution of the difference pattern anti-symmetrical. It is proposed that if the semi-aperture technique (SAT) is used in the

Appropriate change technique (ACT) is applied to a phased array antenna in this paper. Its concept evolves from the appropriate random technique (ART) for amplitude quantization, now that we use ACT in other subjects. Studies show that ACT can provid
