## Abstract

An antenna system includes a first antenna element and a second antenna element. The first antenna element includes a first ground element, a first radiation element, a second radiation element, and a third radiation element. The first radiation element has a first feeding point. The second radiation element is coupled to the first ground element. The third radiation element is coupled to the first ground element. The third radiation element is adjacent to the first radiation element and the second radiation element. The second antenna element includes a second ground element, a fourth radiation element, a fifth radiation element, and a sixth radiation element. The fourth radiation element has a second feeding point. The fifth radiation element is adjacent to the fourth radiation element. The fifth radiation element is coupled through the sixth radiation element to the second ground element.
