Claim 13:
14. The antenna array according to claim 1, wherein
the on-elements adjacent to each other in a vertical direction in the two-dimensional array are defined as first on-elements,
the first on-elements adjacent to each other are grouped and controlled by the phase shifter,
the plurality of antenna elements includes off-elements that are not electrically connected to the phase shifter,
a single on-element electrically connected to a single phase shifter is defined as a second on-element,
the second on-elements are arranged so as to be separated from each other in a same direction as a direction toward which the first on-elements are grouped,
the second on-elements are provided as a null filter and arranged line-symmetrically with respect to a center of the antenna array at an interval of (0.5+m) λ (provided that m=1, 2, . . . ).
