ANTENNA STRUCTURE

An antenna structure (100) includes a ground element (110), a feeding radiation element (120), a first radiation element (130), a second radiation element (140), a third radiation element (150), and a switch circuit (160). The ground element (110) provides a ground voltage. The feeding radiation ele...

Summary:An antenna structure (100) includes a ground element (110), a feeding radiation element (120), a first radiation element (130), a second radiation element (140), a third radiation element (150), and a switch circuit (160). The ground element (110) provides a ground voltage. The feeding radiation element (120) has a feeding point. The feeding radiation element (120) is coupled through the first radiation element (130) to the second radiation element (140). The third radiation element (150) is coupled to the feeding radiation element (120). The feeding radiation element (120) is disposed between the first radiation element (130) and the third radiation element (150). The switch circuit (160) selectively couples the second radiation element (140) to the ground voltage according to a control voltage. A slot (170) is formed and surrounded by the ground element (110), the feeding radiation element (120), the first radiation element (130), and the second radiation element (140).
