Abstract: An antenna structure includes a feeding radiation element, a first radiation element, a second radiation element, a shorting element, a first tuner, and a second tuner. The feeding radiation element has a feeding point. The first radiation element is coupled to the feeding radiation element. The first radiation element is coupled through the first tuner to a ground voltage. The feeding radiation element is coupled through the shorting element to the ground voltage. The second radiation element is adjacent to the first radiation element, and is separated from the first radiation element. The second radiation element is coupled through the second tuner to the ground voltage. The feeding radiation element is disposed between the first tuner and the shorting element.

Abstract: An antenna structure includes a first ground element, a feeding element, a shorting element, a parasitic tuning element, a second ground element, a first parasitic element, a second parasitic element, and a dielectric substrate. The feeding element is coupled through the shorting element to the first ground element. The parasitic tuning element is coupled to the first ground element. The parasitic tuning element is at least partially surrounded by the feeding element, the shorting element, and the first ground element. The second ground element is adjacent to the feeding element. The first parasitic element and the second parasitic element are coupled to the second ground element. The feeding element, the shorting element, the parasitic tuning element, the first parasitic element, the second parasitic element, and at least one of the first ground element and the second ground element are disposed on the dielectric substrate.

Abstract: A mobile device includes a metal mechanism element, a dielectric substrate, a holder, a feeding radiation element, a ground plane, a shorting element, a circuit element, a first parasitic radiation element, a second parasitic radiation element, and an additional radiation element. The metal mechanism element has a slot. The ground plane and the shorting element are respectively coupled to the metal mechanism element. The circuit element is coupled between the shorting element and the ground plane. The first parasitic radiation element and the second parasitic radiation element are respectively coupled to the ground plane. The additional radiation element is adjacent to the feeding radiation element or is coupled to the feeding radiation element. An antenna structure is formed by the feeding radiation element, the circuit element, the first parasitic radiation element, the second parasitic radiation element, the additional radiation element, and the slot of the metal mechanism 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.
