Abstract: An antenna device includes a metal mechanism element, a ground plane, a feeding element, a grounding extension element, and a dielectric substrate. The metal mechanism element has a slot. The feeding element has a feeding point coupled to a signal source. The feeding element extends across the slot. The grounding extension element is coupled to the ground plane. A vertical projection of the grounding extension element at least partially overlaps the slot. An antenna structure is formed by the feeding element, the grounding extension element, and the slot of the metal mechanism element. The antenna structure is capable of covering a low-frequency band and a high-frequency band. The distance between the feeding point and one end of the slot is less than or equal to 0.1 wavelength of a central frequency of the low-frequency band.

Abstract: An antenna structure includes a metal mechanism element, a ground element, a feeding radiation element, a first radiation element, a second radiation element, a parasitic radiation element, a tuning circuit, and a nonconductive support element. The metal mechanism element has a slot. The metal mechanism element includes a first grounding portion and a second grounding portion. The slot is positioned between the first grounding portion and the second grounding portion. The feeding radiation element has a feeding point. The first radiation element is coupled to the feeding radiation element. The second radiation element is coupled to the feeding radiation element. The parasitic radiation element is coupled to the ground element. The parasitic radiation element is adjacent to the first radiation element and the second radiation element. The tuning circuit is coupled between the first grounding portion and the second grounding portion of the metal mechanism element.
