Abstract: An antenna comprises a ground element, a transmission element, a conductive element and a coupling element. The conductive element connects the ground element and the transmission element. The coupling element extends from the conductive element substantially parallel to the transmission element, wherein the coupling element is located on a first plane, the transmission element is located on a second plane, and the second plane is parallel to the first plane.

Abstract: A broadband antenna for wireless signal transmission of an electronic device is disclosed. The broadband antenna has a radiating element, a grounding element, a short-circuiting element and a feeding plane. The radiating element has a first radiation area and a second radiation area, the first radiation area and the second radiation area perpendicularly connected to each other substantially. The feeding plane perpendicularly connected to the second radiation area substantially, the feeding plane comprising a feeding point, a first end and a second end; wherein a distance between the feeding point and the first end is less than a distance between the feeding point and the second end. The short-circuiting element is used for connecting the first radiation area with the grounding element or connecting the feeding plane with the grounding element.

Abstract: A triple-band antenna for an electronic device with a communication capability comprises a first radiating body, a second radiating body, a metal base and a signal feed source. A dual-band antenna for low frequency and high frequency bands may be formed by the first radiating body. A middle-frequency band antenna and a balun may be formed by the combination of the first radiating body and the second radiating body, and the balun may be used to increase the bandwidth of operating frequencies of the intermediate frequency band antenna.

Abstract: A disc accessing apparatus and its panel are provided. The disc accessing apparatus includes a housing, a panel with an opening for a disc to pass, a surface slanted towards the opening and an engagement portion. When a disc cannot be ejected from the disc accessing apparatus normally, the surface leads the disc out. In case the disc cracks into pieces during high-speed rotation, the pieces strike the surface to generate a force that makes the engagement portion and the housing engage more tightly.

Abstract: An optical disk drive includes a base for holding an optical disk, a protrusion protruding out from the base that extends through the center hole of the optical disk when holding the optical disk, and at least one hook rotatably installed on the protrusion. When the disk drive stops, the hook is retracted to within the edge of the protrusion and when disk is rotated up to a predetermined speed, the hook extends out from the edge of the protrusion to hook the optical disk.
