An antenna structure includes a ground element, a feeding radiation element, a first radiation element, a second radiation element, a shorting radiation element, a third radiation element, a filter circuit, a proximity sensor, and a tuning circuit. The ground element provides a ground voltage. The feeding radiation element has a feeding point. The first radiation element and the second radiation element are coupled to the feeding radiation element, or are disposed adjacent to the feeding radiation element. The first radiation element is also coupled through the shorting radiation element to the ground voltage. The third radiation element is disposed adjacent to the first radiation element. The third radiation element is coupled through the filter circuit to the proximity sensor. The filter circuit is also coupled through the tuning circuit to the ground voltage.
