<p>PURPOSE:To reduce a measuring error while keeping a wide automatic tracking range by forming hybrid circuits connected to antenna component bodies in respective groups and settng up the beam width of radio waves narrowly in the altitude angle direction and widely in the bearing angle direction. CONSTITUTION:The antenna component bodies 1-8 are divided into two parts respectively in the vertical direction (altitude angle direction) and the horizontal direction (bearing angle direction) to form four pairs (A-D groups) of antenna component body groups. Respective antenna component bodies 1,2-7,8 constituting the A-D groups are connected to the hybrid circuits 15-18 in a signal composing part or a signal branching part 101. The hybrid circuits 15-18 are formed in each group so that the beam width of radio waves is made narrow in the altitude angle direction and wide in the bearing angle direction. Thus, the automatic tracking antenna which can reduce the measuring error while keeping a wide automatic tracking range in the bearing angle direction.</p> |
