Mobile device supporting wideband operation

A mobile device supporting wideband operations, comprising:

• a first metal mechanism element, comprising a main portion and a sidewall portion, wherein the sidewall portion has a first slot;
• a dielectric substrate, disposed adjacent to the sidewall portion of the first metal mechanism element;
• a first feeding radiation element, coupled to a feeding point, and extending across the first slot of the first metal mechanism element;
• a second feeding radiation element, coupled to the feeding point, and extending across the first slot of the first metal mechanism element, wherein the first feeding radiation element and the second feeding radiation element are disposed on the dielectric substrate;
• a ground element, coupled to the main portion of the first metal mechanism element, wherein an antenna structure is formed by the first slot of the first metal mechanism element, the dielectric substrate, the first feeding radiation element, the second feeding radiation element, and the ground element;
• and
• a second metal mechanism element, disposed opposite to the main portion of the first metal mechanism element, wherein the second metal mechanism element has a second slot;
• wherein the first feeding radiation element comprises a first segment coupled to the feeding point, and a second segment coupled to the first segment;
• wherein the second feeding radiation element comprises a third segment coupled to the feeding point, and a fourth segment coupled to the third segment;
• wherein a combination of the first segment and the third segment has a V-shape.
