<p>PURPOSE:To provide a phased array antenna device with little crossover loss, small tracking error and excels in automatic tracking function and is small in device dimensions. CONSTITUTION:The offset angle of a beam is corrected by a beam width correction circuit 8 for correcting the charge of a beam at the time of scanning a beam for an angle error signal calculated in an angle error calculating circuit 7 based on a signal level received by a receiver in a state that a beam is offset in a positive direction and a negative direction. With such a constitution that the angle is provided to an angle command circuit 5, a control circuit 4 is operated to make a beam track a target with accuracy.</p> |
