摘要: The present invention relates to an antenna arrangement for a portable radio communication device including casing, said casing housing generally planar printed circuit (1) board defining ground plane device. comprises: first element (4; 5) transmission of signals mountable within and connectable board; second (7; 9; 11) reception board. element, when mounted above board, has projection on which is perpendicular parallel wherein size positioned such that extends, in all directions plane, farther than the projection, at least by distance one millimeter. With it possible increase power level without increasing SAR.
