Abstract: An antenna structure includes a ground element, a first radiation element, a second radiation element, a first feeding element, and a second feeding element. The first radiation element is positioned between the second radiation element and the ground element. The first feeding element includes a first coupling excitation element. The second feeding element includes a second coupling excitation element. The first coupling excitation element and the second coupling excitation element are both adjacent to the first radiation element. A first line segment is formed by connecting a central point of the first coupling excitation element to a central axis of the antenna structure. A second line segment is formed by connecting a central point of the second coupling excitation element to the central axis of the antenna structure. An angle between the first line segment and the second line segment is greater than 90 degrees.
