Abstract
An antenna structure includes a main ground element, an extension ground element, a feeding radiation element, a first radiation element, a second radiation element, a shorting radiation element, a third radiation element, and a dielectric substrate. The extension ground element is coupled to the main ground element. A notch region is defined by the main ground element and the extension ground element. The feeding radiation element has a feeding point. The first radiation element is coupled to the feeding radiation element. The second radiation element is coupled to the feeding radiation element. The second radiation element and the first radiation element substantially extend in opposite directions. The feeding radiation element is also coupled through the shorting radiation element to the extension ground element. The third radiation element is coupled to the main ground element.
