Abstract
An antenna structure includes a nonconductive supporting element, a feeding radiation element, a first radiation element, a second radiation element, a third radiation element, and a fourth radiation element. The first radiation element is coupled to a ground voltage. A first coupling gap is formed between the first radiation element and the feeding radiation element. The second radiation element is coupled to the first radiation element. A second coupling gap is formed between the second radiation element and the feeding radiation element. The third radiation element is coupled to the first radiation element. The fourth radiation element is coupled to the ground voltage. A third coupling gap is formed between the fourth radiation element and the feeding radiation element. The feeding radiation element, the first radiation element, the second radiation element, the third radiation element, and the fourth radiation element are all disposed on the nonconductive supporting element.
