PROBLEM TO BE SOLVED: To form a null in a direction you do not want to direct a beam, while keeping the main beam direction, or to form a beam furthermore in a direction different from the main beam direction.SOLUTION: An antenna device includes a plurality of antenna elements 10, phase shifters 11 provided corresponding to the antenna elements 10, respectively, and a control unit 20. The control unit 20 includes a phase set value storage section for storing a phase set value to be set in each phase shifter 11, for each combination of beam direction and null direction, or each combination of first beam direction and second beam direction, and a phase determining section for setting a phase set value 110 corresponding to the input information to be stored in a phase set value storage section in each phase shifter 11, according to the input information of beam direction and null direction, or the input information of first beam direction and second beam direction. |
