|1. (WO2002005381) ANTENNA ARRANGEMENT AND PORTABLE RADIO COMMUNICATION DEVICE|
|Applicants:||ALLGON MOBILE COMMUNICATIONS AB
|Title:||ANTENNA ARRANGEMENT AND PORTABLE RADIO COMMUNICATION DEVICE|
The present invention relates to an antenna arrangement for a portable radio communication device including a casing, said casing housing a generally planar printed circuit (1) board defining a ground plane device. The antenna arrangement comprises: a first antenna element (4; 5) for transmission of radio signals mountable within said casing and connectable to said printed circuit board; and a second antenna element (7; 9; 11) for reception of radio signals mountable within said casing and connectable to said printed circuit board. The first antenna element, when mounted above said printed circuit board, has a projection on said printed circuit board, which is perpendicular to a plane parallel to said generally planar printed circuit board, wherein said first antenna element has a size and is positioned such that said printed circuit board extends, in all directions of said plane, farther than the projection, at least by a distance of one millimeter. With such an antenna arrangement it is possible to increase the power level a portable radio communication device without increasing SAR.
