Abstract: An antenna structure includes a first radiator, a second radiator, a third radiator and a fourth radiator. The first radiator and the second radiator are arranged along a first direction, and the second radiator and the third radiator are arranged along a second direction perpendicular to the first direction. The first radiator, the second radiator and the third radiator are circularly polarized radiators in the same rotational direction, and the fourth radiator is a circularly polarized radiator in a rotational direction opposite to that of the first radiator, the second radiator and the third radiator.
