Antenna structure

摘要

An antenna structure has a first resonance mode and a second resonance mode. The antenna structure consists of a first radiation element, a second radiation element, a grounding element, and a signal feeding element. The first radiation element resonates at a first operating frequency band corresponding to the first resonance mode. The second radiation element is extended from a first end of the first radiation element and resonates at a second operating frequency band corresponding to the second resonance mode. The grounding element is extended from a second end of the first radiation element. The signal feeding element is disposed between the first radiation element and the grounding element. The second radiation element, the first radiation element, and the grounding element are formed by bending a slender metal sheet.

1. 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.
