Abstract (en)
[origin: EP0473875A1] An RF magnetic coil device, for example a ring-core transmitter, in miniature or chip construction, having a base body (1) of plastic which has recesses for magnetic cores (2) and contains electrical conductor tracks (5) on its upper side (10) and its lower side (11) and, in its interior, is provided with through-plated holes (16) to which the conductor tracks (5) are connected such that individual turns are formed around the magnetic core which produce windings of coils (6, 7). In addition, methods are specified which allow these devices to be produced in large quantities. <IMAGE>
