Transmit adaptive phased array antenna system and receive adaptive phased array antenna system are disclosed which include a transmitter unit; a power divider unit which is connected to the transmitter unit, and when transmitting, divides computed weights; a receiver unit; an array antenna unit wherein multiple basic elements of antenna are spatially arrayed; a power feeder unit which, at the time of receiving, receives receive signal of the array antenna unit and changes amplitude and phase of the receive signal according to another control signal, and at the time of transmitting, receives divided signal from the power divider unit; a power combiner unit which sums receive signals, which are received from the power feeder unit, by using weights; an amplitude detector unit which checks the amplitude of the signals which are received from the power combiner unit, and transmits them to the receiver unit; a beam control unit which receives a portion of the amplitude of summed signals from the amplitude detector, and adjusts beam direction of the antenna, and compares field intensity which is received from each direction, and finds optimized path; and a weight memory unit which is commanded by the beam controller unit to provide power feeder unit with weights which befit their directions.
