Antenna element and electronic device

An electronic device, comprising an antenna element, the antenna element comprising:

• a first radiator and a grounding component, wherein in a height direction of the antenna element, the first radiator is spaced from a ground plane and disposed opposite to the ground plane, and the first radiator is connected to the ground plane through the grounding component;
• a second radiator, wherein the second radiator is spaced from the first radiator, and in the height direction of the antenna element, the second radiator is spaced from the ground plane and disposed opposite to the ground plane;
• and
• a radiator array, wherein in the height direction of the antenna element, the radiator array is spaced from the first radiator and disposed opposite to the first radiator, and the radiator array is located on a first side that is of the first radiator and that is further from the ground plane than a second side of the first radiator that is closest to the ground plane;
• and the radiator array comprises at least two sub-radiators, and the at least two sub-radiators are spaced from each other in an extension direction of a plane on which the radiator array is located, wherein
• the first radiator comprises a first hollow region, and the radiator array comprises a second hollow region;
• a plane parallel to a plane on which the ground plane is located is used as a projection plane, a projection of the first radiator on the projection plane is a first projection, a projection of the second radiator on the projection plane is a second projection, and a projection of the radiator array on the projection plane is a third projection;
• and the first projection and the third projection at least partially overlap, at least a part of the second projection is located within a contour line formed by the first hollow region on the projection plane, and at least a part of the second projection is located within a contour line formed by the second hollow region on the projection plane;
• and
• the first radiator comprises a first feeding connection point, the second radiator comprises a second feeding connection point, the first feeding connection point is connected to a first feed point, and the second feeding connection point is connected to a second feed point.
