Abstract
An antenna structure includes a ground plane, a first feeding element, a second feeding element, a connection element, a first radiation element, a second radiation element, a third radiation element, a first tuning circuit, a second tuning circuit, a third tuning circuit, and a fourth tuning circuit. The ground plane has a notch region. The first tuning circuit is coupled between a signal source and the first feeding element. The second tuning circuit is coupled between the first feeding element and the second feeding element. The third tuning circuit is coupled between the second feeding element and the ground plane. The first radiation element is coupled to the first feeding element. The fourth tuning circuit is coupled between the first radiation element and the ground plane. Both the second radiation element and the third radiation element are coupled through the connection element to the second feeding element.
