A mobile device includes a first nonconductive supporting element, a second nonconductive supporting element, and an antenna structure. The first nonconductive supporting element and the second nonconductive supporting element are adjacent to each other. The first nonconductive supporting element and the second nonconductive supporting element have different heights. The antenna structure is formed on the first nonconductive supporting element and the second nonconductive supporting element. The antenna element includes a feeding connection element, a first radiation element, and a second radiation element. The feeding connection element is coupled to a feeding point. The first radiation element and the second radiation element are coupled to the feeding connection element. The feeding connection element is disposed between the first radiation element and the second radiation element.
