Abstract
A mobile device includes a metal back cover, a display device, a display frame, a nonconductive filling element, a dielectric substrate, a ground element, and a radiator. The metal back cover has a slot. The display device and the display frame are disposed opposite to the metal back cover. The nonconductive filling element is at least partially embedded in the slot. The dielectric substrate is disposed on the nonconductive filling element. The ground element is coupled to the metal back cover. The radiator is coupled to the ground element and is disposed on the dielectric substrate. An antenna structure is formed by the radiator and the slot of the metal back cover. The distance from the slot to an edge of the metal back cover is shorter than 10 mm.
