Abstract: A mobile device includes a supporting element, a ground element, and an antenna structure. The antenna structure includes a first feeding radiation element, a second feeding radiation element, a first parasitic radiation element, a second parasitic radiation element, and a third parasitic radiation element. The first feeding radiation element and the second feeding radiation element are both coupled to a signal feeding point. Each of the first parasitic radiation element, the second parasitic radiation element, and the third parasitic radiation element is coupled to the ground element. A first coupling gap is formed between the first parasitic radiation element and the first feeding radiation element. A second coupling gap is formed between the second parasitic radiation element and the first feeding radiation element. A third coupling gap is formed between the third parasitic radiation element and the second feeding radiation element.

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: A communication device includes a metal mechanism element, a feeding radiation element, a tuning radiation element, and a dielectric substrate. The metal mechanism element has a closed slot. The feeding radiation element extends across the closed slot. The feeding radiation element has a feeding point. The tuning radiation element extends across the closed slot. The first end of the tuning radiation element is coupled to the metal mechanism element. The second end of the tuning radiation element is adjacent to the metal mechanism element or is coupled to the metal mechanism element. The dielectric substrate is adjacent to the metal mechanism element. The feeding radiation element and the tuning radiation element are both disposed on the dielectric substrate. An antenna structure is formed by the feeding radiation element, the tuning radiation element, and the closed slot of the metal mechanism element.
