  • Publication number: 20090135579
    Abstract: A touch pad including an ElectroMagnetic Interference (EMI) shielding plate and method for detecting a touch on the touch pad is provided. The touch pad includes a touch plate for generating, when a touch is generated on a surface of the touch plate, a change of a physical property, a touch sensor coupled to the touch plate for detecting a position of the generated touch by measuring the change of the physical property, and an EMI shielding plate disposed adjacent to or attached to a surface of the touch plate and formed with a plurality of openings. The density of the openings formed at a position of the EMI shielding plate increases as the position becomes farther from the touch sensor. Accordingly, the touch pad having an EMI shielding plate can more accurately detect a touch generated at any position close to or remote from the touch sensor of the touch pad, and thereby increase user convenience of a portable terminal.

  • Patent number: 6795038
    Abstract: Disclosed is an interface connection cable antenna installed between a mobile communication terminal and an external terminal to transmit data at high speed, which is capable of easily implementing a desired space diversity in the data transmission. The interface connection cable antenna includes a plug pin plate to be coupled to an external interface connector included in the mobile communication terminal, an interface plug having embedded therein an antenna plug to be coupled to an antenna connector included in the mobile communication terminal, and an antenna connected to the antenna plug via the interface plug, the antenna having a desired length. The interface cable is connected at one end thereof to a connector coupled to a data port included in an external terminal while being provided at the other end thereof with at least one wire connected to the plug pin plate via the interface plug.
