  • Portable terminal
    Patent number: 8049670
    Abstract: A portable terminal may include a terminal body, a printed circuit board having a ground unit coupled to an antenna, and an electric field reducing unit to transfer a current flowing in the ground unit to a side surface of the terminal body and to reduce strength of an electric field.
    Type: Grant
    Filed: February 27, 2009
    Date of Patent: November 1, 2011
    Assignee: LG Electronics Inc.
    Inventors: Kang-Jae Jung, An-Sun Hyun, Chang-Won Yun
  • Antenna and mobile terminal
    Patent number: 7868836
    Abstract: An antenna for a mobile terminal includes a substrate, a dipole placed on the substrate, a loop placed on the substrate, and a matching circuit on the substrate. The matching circuit comprises at least one of a variable capacitor or a variable inductor. The radiation center of the loop substantially coincides with the radiation center of the dipole.

  • PORTABLE TERMINAL
    Publication number: 20090243944
    Abstract: A portable terminal is provided that includes a terminal body having a receiver, a ground unit connected to an antenna mounted at the terminal body, and an electric field reducing unit connected to the ground unit and partially transferring a current flowing in the ground unit to a side surface of the terminal body. The strength of the electric field formed at the periphery of the receiver of the portable terminal may be reduced, thus minimizing interference between the portable terminal and the hearing aid.
