ABSTRACT:
Disclosed is an inductive miniature structural element, particularly an antenna. Said structural element comprises a winding member (1) which is embodied as a flat component and on which three coil windings (2X,2Y,2Z) are mounted in such a way that the axes of said coil windings point in the three three-dimensional directions (X, Y, Z). The winding member (1) is made at least in part of ferrite material while the top face and the bottom face thereof are provided with guiding elements (1.5, 1.6, 1.7, 1.8) for directing the third coil winding. The winding member (1) is placed on a coil plate (3) made of electrically non-conducting, non-ferromagnetic material and is connected thereto. The coil plate (3) is provided with recesses into which the guiding elements that are located on the bottom face of the winding member (1) engage. The ends of the first and second coil winding (2X,2Y) are wound around the guiding elements located on the bottom face of the winding member, respectively, while the ends of the third coil winding (2Z) are wound around corners or projections of the coil plate (3), respectively.
