Mobile device

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, and they have different heights. The antenna structure is formed on the first nonconductive supporting element and the second nonconductive supporting element. The antenna structure includes a feeding element, a first connection element, a second connection element, a first radiation element, and a second radiation element. The feeding element is coupled to a feeding point. The first radiation element and the second radiation element are both coupled through the second connection element and the first connection element to the feeding element. The second connection element is positioned between the first radiation element and the second radiation element. The first radiation element and the second radiation element extend in different directions.
