An antenna structure includes a ground element, a metal cavity, a first radiation element, a second radiation element, a third radiation element, and a capacitive element. The metal cavity includes a first edge segment and a second edge segment which are opposite to each other. The first edge segment is coupled to the ground element. The first radiation element has a feeding point. The first radiation element is adjacent to the second edge segment. The second radiation element is coupled to the first edge segment. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to the second edge segment. The capacitive element is coupled between the first edge segment and the second edge segment. The first radiation element, the second radiation element, and the third radiation element are disposed between the first edge segment and the second edge segment.
