摘要
A beam direction controlling unit 9 includes a relative position determining unit 91 that determines a relative position between a reflector antenna 1 and an array antenna 3 by controlling a driver (a driving unit 7 and a drive controlling unit 8) in such a way that a range on the array antenna 3 onto which a parallel light beam 101 from a desired beam direction is reflected by the reflector antenna 1 and is then projected is a range in which element antennas 2 are arranged, an excitation element selector 92 that selects, as element antennas 2 to be excited, element antennas 2a onto which the parallel light beam 101 is projected at the determined relative position between the reflector antenna 1 and the array antenna 3, an excitation amplitude phase determining unit 93 that sets an excitation amplitude phase of the selected element antennas 2, and sets the excitation amplitude phase to an excitation amplitude phase controller (an amplitude controller 4, a phase shifter 5, and an excitation amplitude phase controlling unit 6), and a transmitter receiver connecting unit94 that connects the selected element antennas 2 to a transmitter receiver.
