  • Mobile terminal with two antennas for reducing the RF radiation exposure of the user
    Patent number: 8537057
    Abstract: For a mobile terminal for receiving wireless transmissions from a transmitter and transmitting wireless transmissions to a receiver it proposed to provide an antenna arrangement having a plurality of antenna elements each provided on or within a common body or a respective body of the terminal in a defined spatial relation to a conducting chassis part, wherein at least one first antenna element is located on a first side and at least one second antenna element is located on a second side of the same conductive chassis part or of the respective conducting chassis part, wherein high frequency circuitry, for transmitting a respective wireless transmission, is adapted to simultaneously drive said first antenna element and said second antenna element by feeding the same or corresponding high frequency signals to said first antenna element and to said second antenna element.

  • Radio communication device and associated coupling structure comprising at least one conductor board and at least one flat antenna coupled thereto
    Publication number: 20060019696
    Abstract: A radio communication device is provided which includes a conductor board and a flat antenna disposed in the housing thereof and arranged at a distance from each other, thereby forming a coupling structure. A coupling area with a predetermined antenna volume is contained in the coupling structure between the antenna and the conductor board. At least one camera is arranged in, or adjacent to, the coupling area of the coupling structure such that they simultaneously form a component of the antenna volume of the coupling structure.
