Abstract

A mobile device includes a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, a fifth radiation element, and a dielectric substrate. The first radiation element and the third radiation element are coupled to a signal source. The second radiation element is coupled to a ground voltage. The second radiation element is adjacent to the first radiation element. The first radiation element, the second radiation element, and the third radiation element substantially extend in the same direction. The fourth radiation element is coupled to the ground voltage. The fourth radiation element is between the first radiation element and the second radiation element. The fifth radiation element is coupled to the ground voltage. An antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, the fourth radiation element, the fifth radiation element, and the dielectric substrate.
