Abstract
An antenna comprising a rectangular reflector; first and second dipole antennae disposed in front of the reflector and aligned parallel to the long edge of the reflector; rod-shaped first metal conductors arranged parallel to the first and second dipole antennae and separated from the dipole antennae by a distance X1 to the outside in the direction parallel to the short edge of the reflector, and separated by a distance Y1 in the direction perpendicular to the reflector; and rod-shaped second metal conductors disposed at a position separated from the dipole antennae by a distance X2 greater than distance X1 to the outside with respect to each other, and separated by a distance Y2 greater than distance Y1 forward in the direction perpendicular to the reflector.
