PROBLEM TO BE SOLVED: To provide an antenna system that aggregates slot antennas, has a polarization diversity function, simplifies the configuration of a feeding means and obtains a broad band characteristic with a small size, high performance and a high efficiency. SOLUTION: In the antenna system where slots are formed to a conductor plate 3 layered on a dielectric board 2 to configure antenna elements, two straight line parts 4c, 4d linearly extended with a prescribed width are orthogonal to each other in the middle in the respective length directions to form a slot 4 so as to configure a couple of the antenna elements 1, a 1st feeding line 5 at an angle of +45 deg. with respect to the straight line part 4b and a 2nd feeding line 6 at an angle of -45 deg. with respect to the straight line part 4b are placed along the dielectric board 2 so as to pass through a crossing part 4a of the straight line parts 4c, 4d respectively, the one feeding line 2 is placed on one side of the dielectric board 2 and the other feeding line 6 is placed on the other side of the dielectric board 2 in the vicinity of the crossing part 4a.
