Patent ID: 8816926

Claim:
An antenna structure, having at least a first resonance mode and a second resonance mode, the antenna structure comprising: a first radiation element, for resonating at a first operating frequency band corresponding to the first resonance mode; a second radiation element, extended from a first end of the first radiation element, for resonating at a second operating frequency band corresponding to the second resonance mode; a grounding element, extended from a second end of the first radiation element; and a signal feeding element, disposed between the first radiation element and the grounding element; wherein each of a first section of the first radiation element, a second section of the second radiation element, and a third section of the grounding element substantially parallels and at least partially overlaps with the others in an X axis; and, the second end of the first radiation element is an opposite end of the first radiation element compared to the first end of the first radiation element in the X axis; the second radiation element includes a section which is parallel to the second section of the second radiation element and substantially in a same plane as the first section of the first radiation element.
