The utility model relates to an antenna structure. Particularly, the antenna structure comprises a base plate, a radiating component, a signal feed component and a grounding component. The radiating component comprises a first radiator and a second radiator coupled with the first radiator; the first radiator and the second radiator are completely same; and the signal feed component is coupled at the connection part of the first radiator and the second radiator which are arranged at the two sides of the signal feed component so as to form an array in a left-right symmetrical manner. The grounding component comprises a first grounding subcomponent and a second grounding subcomponent, wherein the first grounding subcomponent is coupled between the first radiator and the base plate, the second grounding subcomponent is coupled between the second radiator and the base plate, and the first grounding subcomponent and the second grounding subcomponent are same completely. The antenna structure achieves the effect of simultaneously receiving left-handed circular polarized signals and right-handed circular polarized signals by a single antenna structure, can greatly reduce product thickness, also can reduce manufacturing cost, and has good voltage standing-wave ratio and radiation efficiency and wide magnetic field direction.
