Abstract
An antenna structure with multiple frequency capabilities applied to an electronic device includes frame body, first feed point, a first switch point, and second switch point. The frame body has at least one portion made of metal material and defines two gaps. The frame body between gaps form a first radiation portion. The first feed point from a source feeds current and signal to the first radiation portion. The first switch point and the second switch point are located at two ends of the frame body adjacent to the first gap. The first switch point and the second switch point are grounded through a switch circuit.
Claims20
An antenna structure applied to an electronic device, the antenna structure comprising:
- a frame body with at least one portion made of metal material, wherein the frame body defines a first gap and a second gap, the frame body between the first gap and the second gap form a first radiation portion;
- a first feed point positioned on the first radiation portion and being electrically connected to a first feed source for feeding current and signal to the first radiation portion;
- a first switch point;
- and
- a second switch point;
- wherein the frame body further defines a third gap, the frame body between the first gap and the third gap forms a second radiation portion,
- wherein the first switch point is disposed at a first end of the first radiation portion close to the first gap, and is grounded through a first switch circuit, the second switch point is disposed at a second end of the second radiation portion close to the first gap and is grounded through a second switch circuit.
