The first metal mechanism element includes a main portion and a sidewall portion. The sidewall portion of the first metal mechanism element has a first slot. Both the first feeding radiation element and the second feeding radiation element extend across the first slot of the first metal mechanism element. 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. The second metal mechanism element is disposed opposite to the main portion of the first metal mechanism element. The second metal mechanism element has a second slot. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The mobile device as claimed in claim 1, wherein the first slot of the first metal mechanism element is a first closed slot. ### Claim 3 (depends on 2) The mobile device as claimed in claim 2, wherein the second slot of the second metal mechanism element is a second closed slot. ### Claim 4 (depends on 3) The mobile device as claimed in claim 3, wherein the first closed slot and the second closed slot are substantially parallel to each other. ### Claim 5 (depends on 1) The mobile device as claimed in claim 1, wherein an angle is formed between the first feeding radiation element and the second feeding radiation element. ### Claim 6 (depends on 5) The mobile device as claimed in claim 5, wherein the angle is from 30 to 90 degrees. ### Claim 7 (depends on 1) The mobile device as claimed in claim 1, wherein the antenna structure covers a first frequency band, a second frequency band, and a third frequency band. ### Claim 8 (depends on 7) The mobile device as claimed in claim 7, wherein the first frequency band is from 2400 MHz to 2500 MHz, the second frequency band is from 5150 MHz to 5850 MHz, and the third frequency band is from 5925 MHz to 7125 MHz. ### Claim 9 (depends on 7) The mobile device as claimed in claim 7, wherein a length of the first slot of the first metal mechanism element is substantially equal to 0.5 wavelength of the first frequency band. ### Claim 10 (depends on 7) The mobile device as claimed in claim 7, wherein a length of the second slot of the second metal mechanism element is substantially equal to 0.5 wavelength of the first frequency band. ### Claim 11 (depends on 7) The mobile device as claimed in claim 7, wherein a length of the first feeding radiation element is substantially equal to 0.25 wavelength of the third frequency band. ### Claim 12 (depends on 7) The mobile device as claimed in claim 7, wherein a length of the second feeding radiation element is substantially equal to 0.25 wavelength of the third frequency band. ### Claim 13 (depends on 1) The mobile device as claimed in claim 1, further comprising: a nonconductive support element, filling the first slot of the first metal mechanism element, wherein the nonconductive support element is configured to carry the dielectric substrate. ### Claim 14 (depends on 1) The mobile device as claimed in claim 1, wherein the second metal mechanism element further has a cutting retraction design. ### Claim 15 (depends on 14) The mobile device as claimed in claim 14, wherein the cutting retraction design of the second metal mechanism element is not parallel to the main portion of the first metal mechanism element. ### Claim 16 (depends on 1) The mobile device as claimed in claim 1, wherein a first obtuse angle is formed between the first segment and the second segment. ### Claim 17 (depends on 1) The mobile device as claimed in claim 1, wherein a second obtuse angle is formed between the third segment and the fourth segment.
