Abstract
An antenna system includes a first antenna structure which includes a first ground element, a first radiation element, a second radiation element, and a third radiation element. The first radiation element is coupled to the first ground element. A region is defined by the first ground element and the first radiation element. The second radiation element has a first feeding point. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to the first feeding point. The third radiation element is adjacent to the first ground element. The second radiation element and the third radiation element are disposed inside the aforementioned region.
