An antenna structure includes a ground element, a feeding radiation element, a connection radiation element, a grounding radiation element, a shorting radiation element, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, and a nonconductive support element. The feeding radiation element has a positive feeding point. The first radiation element and the second radiation element are coupled to the feeding radiation element. The second radiation element is at least partially surrounded by the first radiation element. The grounding radiation element has a negative feeding point. The grounding radiation element is coupled through the connection radiation element to the feeding radiation element. The shorting radiation element is coupled to the ground element. The third radiation element and the fourth radiation element are coupled to the shorting radiation element. The fourth radiation element is at least partially surrounded by the third radiation element.
