Abstract

See full text

An antenna device comprises a plurality of antennas. The antennas include first antennas which form a first array and second antennas which form a second array. The first antennas include two first predetermined antennas arranged along a first line. A longitudinal direction of one of the first predetermined antennas and another longitudinal direction of a remaining one of the first predetermined antennas intersect with each other and define a horizontal plane. Each first antenna mainly radiates a horizontally polarized wave which is in parallel to the horizontal plane. Each second antenna mainly radiates a vertically polarized wave which is perpendicular to the horizontal plane. The second antennas include two second predetermined antennas arranged along a second line. When the first and second lines are projected onto the horizontal plane along a direction perpendicular to the horizontal plane, the first and second lines intersect with each other.
