Abstract: An antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, a nonconductive support element, and an accessory element. The feeding radiation element has a feeding point. The first radiation element includes a branch portion and a widening portion. The feeding radiation element is coupled through the first radiation element to a ground voltage. The second radiation element is coupled to the feeding radiation element and the first radiation element. The nonconductive support element carries the feeding radiation element, the first radiation element, and the second radiation element. The accessory element includes a nonconductive housing and an internal metal element. The branch portion and widening portion of the first radiation element are disposed on the nonconductive housing of the accessory element.

Abstract: An antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, a fifth radiation element, and a switch circuit. The feeding radiation element has a feeding point. The second radiation element is coupled through the first radiation element to the feeding radiation element. The third radiation element is coupled to the second radiation element. The fourth radiation element is coupled to the second radiation element. The fourth radiation element and the third radiation element extend in different directions. The fifth radiation element has a tuning point, and is coupled to the feeding radiation element. The feeding radiation element is disposed between the first radiation element and the fifth radiation element. The switch circuit selectively couples the tuning point to a ground voltage.

Abstract: An antenna system includes a first antenna element, a second antenna element, and a circuit region. The first antenna element includes a first nonconductive support element and a first main radiation element. The first main radiation element is disposed on the first nonconductive support element. The second antenna element includes a second nonconductive support element and a second main radiation element. The second main radiation element is disposed on the second nonconductive support element. The second main radiation element is at least partially perpendicular to the first main radiation element. The circuit region is positioned between the first antenna element and the second antenna element.
