The present invention relates to an electromagnetic coil structure for being mounted on a magnetic core. Such a magnetic core is for instance a part of a rotating electric machine or of a magneto electronic angle sensor. The present invention further relates to a belonging magnetic core and to a magneto electronic angle sensor, in particular a reluctance resolver. Furthermore, the present invention relates to a method for fabricating such an angle sensor. The coil structure (106) comprises at least one electrically conductive winding formed as a flat conductive track (110), and at least one flexible electrically insulating carrier (112) for carrying said winding. Said coil structure has at least one opening (108) for receiving a magnetic flux guiding element (104) of said core. The circumferential surface of the core whereto said electromagnetic coil structure (106) is mounted has a polygonal shape.
