PROBLEM TO BE SOLVED: To suppress channel correlation to actualize a higher SIR characteristic.SOLUTION: An antenna includes a plurality of antenna elements disposed two-dimensionally on either a plane or a quasi plane, that is, a curved surface capable of approximation to the plane. The plurality of antenna elements, when projected on a predetermined projective axis represented by a straight line on which a vertical plane 22 intersects with a horizontal plane when the antenna is installed, has each projection on the projective axis at substantially equal intervals without mutually overlapped. |
