ABSTRACT:
The scope of the present invention is the antenna arrangement of a radio communication device (87) intended for establishing a two-way connection, with which arrangement it is striven for to reduce the effects of the body on the properties of an antenna and on the other hand to reduce the radiation of the antenna towards the body. The antenna element (81) is planar and it consists of a ground plane and of a radiator (86) essentially parallel to it. The antenna element has been arranged in a position in which the ground plane ends up between the body of the user of the radio communication device and the radiator, and the amplification maximum of the radiation pattern of the antenna is directed away from the user of the radio communication device in an operating position typical of the radio communication device.
