  • Publication number: 20180128924
    Abstract: A wearable electronic device includes a middle frame, a metallic side wall, a dielectric element, and a antenna wiring circuit. The metallic side wall is disposed at one side of the middle frame and has a slot. The dielectric element is disposed at the slot and electrically isolates the metallic side wall and the middle frame. The antenna wiring circuit is disposed at the dielectric element and comprises a antenna pattern. The antenna pattern comprises first and second metal portions. The first metal portion comprises a slit surrounded by first to third segments. The first segment has a signal feeding terminal. The second metal portion is connected to the third segment and is located in the slit. The metallic side wall performs coupled resonant with the first metal portion and the second metal portion to generate a resonant frequency band.

  • Publication number: 20180102589
    Abstract: An antenna system includes a system ground and two antenna units. The two antenna units are individually disposed on two opposite sides of the system ground and symmetrically mirrored with each other. Each antenna unit includes a circuit board, a first antenna pattern and a second antenna pattern. The first antenna pattern is disposed at one side of the circuit board. The first antenna pattern resonates to generate a first high resonant frequency. The second antenna pattern is disposed at the other side of the circuit board. The first antenna pattern resonates with part of the second antenna pattern to generate a low resonant frequency.

  • Patent number: 9640868
    Abstract: A wideband antenna includes a first radiator formed as a part of a metal frame for resonating a first signal component of a radio-frequency signal, a second radiator disposed within an area enclosed by the metal frame for resonating a second signal component of the radio-frequency signal, and a feed terminal electrically connected between the second radiator and a ground for feeding the radio-frequency signal, wherein there is a distance between the first and second radiators such that a coupling effect is induced between the first and second radiators, which allows the first signal component being fed from the second radiator into the first radiator via the coupling effect.

  • Publication number: 20120291506
    Abstract: A device producing a patterned plate includes a die and an electromagnetic actuator. The die includes a patterned surface with a pattern formed thereon and a fracturing part. The tubular work piece is disposed between the die and the electromagnetic actuator such that walls of the tubular work piece correspond to walls of the die. When the electromagnetic actuator is supplied with a current pulse, an eddy current is induced in the tubular work piece, generating a repulsive force between the electromagnetic actuator and the tubular work piece. Therefore, the tubular work piece impacts the die, and a forming surface of the tubular work piece is deformed against the patterned surface and the fracturing part, thus replicating the pattern of the patterned surface onto the forming surface. At the same time, the tubular work piece is fractured at the position corresponding to the fracturing part.

  • Patent number: 8056381
    Abstract: A device for producing a pattern onto a work piece includes a die, an electromagnetic actuator and a base. The die includes a patterned surface, and the patterned surface includes a pattern. The electromagnetic actuator includes an plate body, a convex part and a strip unit connected to the plate body. The electromagnetic actuator is disposed in the base. When the electromagnetic actuator is activated while a work piece is being positioned between the patterned surface and the electromagnetic actuator, an inductive current is generated on the work piece by the electromagnetic actuator, and then a repulsive force is generated between the electromagnetic actuator and the work piece. The repulsive force causes the work piece to adhere to the patterned surface, forcing the work piece to deform against the patterned surface and to take on the shape of the pattern.
