Abstract
An antenna structure includes a ground element, a feeding radiation element, a first radiation element, a second radiation element, a third radiation element, and a switch circuit. The ground element provides a ground voltage. The feeding radiation element has a feeding point. The feeding radiation element is coupled through the first radiation element to the second radiation element. The third radiation element is coupled to the feeding radiation element. The feeding radiation element is disposed between the first radiation element and the third radiation element. The switch circuit selectively couples the second radiation element to the ground voltage according to a control voltage. A slot is formed and surrounded by the ground element, the feeding radiation element, the first radiation element, and the second radiation element.
