  • Apparatus, method and computer program for wireless communication
    Patent number: 8344962
    Abstract: An apparatus comprising: a ground plane configured to receive an antenna, operable in a first resonant frequency band, at a first end of the ground plane; and a member configured to electromagnetically couple with the antenna, provide the ground plane with an electrical dimension, in combination with the antenna, having a resonant mode at the first resonant frequency band, and to reduce current distribution at a second end of the ground plane, different to the first end.
    Type: Grant

    Date of Patent: January 1, 2013
    Assignee: Nokia Corporation
    Inventors: Ping Hui, Rong Bang An, Shu Liu, Wanbo Xie
  • Antenna arrangement
    Patent number: 7834814
    Abstract: An antenna arrangement for radio communication in a first radio communication band and for communication in a second radio communication band including a multiple-resonance antenna element having a feed for connection to radio frequency circuitry; and a load connected to the feed and comprising a plurality of reactive components including a first reactive component that controls the impedance of the load for the first radio communication band and a second reactive component, separate from the first reactive component, that controls the impedance of the load for the second radio communication band wherein the plurality of reactive components of the load are configured to provide an impedance that changes between being inductive at a first frequency in the first radio communication band to being capacitive at a second frequency in the first radio communication band and that changes between being inductive at a third frequency in the second radio communication band to being capacitive at a fourth frequency in th
