Abstract: A mobile device includes a metal back cover and a printed circuit board. The metal back cover has a slot. The printed circuit board includes a dielectric substrate, a first metal element, a second metal element, and via elements. The first metal element is disposed on a top surface of the dielectric substrate. The second metal element is disposed on a bottom surface of the dielectric substrate. The via elements are formed in the dielectric substrate, and are coupled between the first metal element and the second metal element. The first metal element is coupled to the metal back cover, such that a slot antenna is formed by the printed circuit board and the slot of the metal back cover. The slot antenna is excited by a signal source which is coupled to the second metal element.

Abstract: A hinge is provided. The hinge includes a first plate, a second plate, a third plate, a shaft, a first elastic element, and a second elastic element. The second plate is connected to the first plate. The third plate is disposed on the second plate. The shaft is connected to the first plate and the second plate. The first elastic element surrounds the shaft. The second elastic element is connected to the second plate and the third plate. The second plate is rotatable around the shaft via the first elastic element. The second plate is movable relative to the third plate via the second elastic element.
