Abstract (en)
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 (31, 32) each provided on or within a common body (39) or a respective body of the terminal (30) in a defined spatial relation to a conducting chassis part (33), wherein at least one first antenna element (31) is located on a first side and at least one second antenna element (32) is located on a second side of the same conductive chassis part (33) 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 (31) and to said second antenna element (32).
