    摘要: An antenna structure includes a metal mechanism element, a ground element, a feeding radiation element, and a dielectric substrate. The metal mechanism element has a slot. The slot has a first closed end and a second closed end. The ground element is coupled to the metal mechanism element. The feeding radiation element has a feeding point. The feeding radiation element is coupled to the ground element. The dielectric substrate has a first surface and a second surface which are opposite to each other. The feeding radiation element is disposed on the first surface of the dielectric substrate. The second surface of the dielectric substrate is adjacent to the metal mechanism element. The slot of the metal mechanism element is excited to generate a first frequency band and a second frequency band. The feeding radiation element is excited to generate a third frequency band.

    摘要: 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.

    摘要: 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.
