  • Publication number: 20140104134
    Abstract: An antenna structure is provided, including a first radiator, a second radiator, a second coupling portion and a switch Circuit. The first radiator includes a feed portion and a first radiator body. The second radiator includes a first coupling portion, a second radiator body and a ground portion. The first coupling portion is connected to a first end portion of the second radiator body. The ground portion is connected to the second radiator body. At least a portion of the first radiator body is located between the first coupling portion and the second coupling portion. When the antenna structure is in a first mode, the switch circuit forms an electric path between the second radiator and the second coupling portion, and when the antenna structure is in a second mode, the switch circuit removes the electric path between the second radiator and the second coupling portion.

  • Publication number: 20120267715
    Abstract: A high voltage semiconductor device is provided. The device includes a semiconductor substrate having a high voltage well with a first conductivity type therein. A gate structure is disposed on the semiconductor substrate of the high voltage well. A source doped region and a drain doped region are in the high voltage well on both sides of the gate structure, respectively. A lightly doped region with the first conductivity type is between the source and drain doped regions and relatively near to the source doped region. The disclosure also presents a method for fabricating a high voltage semiconductor device.

  • Patent number: 7911390
    Abstract: An antenna structure includes a radiation element, a grounding element, a short point, and a feeding point. The radiation element includes a first radiator and a second radiator. The second radiator partially surrounds the first radiator and there is a predetermined distance included between the first radiator and the second radiator for matching impedance. The short point is coupled between the second radiator and the grounding element. The feeding point is coupled between a joint point of the first radiator and the second radiator and the grounding element.
