Patent 10910698 was granted and assigned to Wistron NeWeb Corporation on February, 2021 by the United States Patent and Trademark Office.
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.
