Abstract
The device has loop antenna element (18) comprising antenna sections (20,22) that are provided in the same plane. The antenna section (24) is provided in another plane parallel to former plane, and the antenna sections (26,28) are provided for interconnecting antenna sections (20,22,24). The antenna sections form a three-dimensional structure with two-dimensional extension in one of the planes. An independent claim is also included for antenna arrangement.
