Abstract (en)
[origin: WO2006015632A1] A transmitting antenna arrangement for emitting a longwave wake-up signal for an ID transmitter in a keyless motor vehicle system. An induction coil (2) comprising at least one winding and a core (3) surrounded by said winding is arranged inside a component (1) of the motor vehicle. The core (3) is shaped as a flat strip and consists of several layers placed on top of each other, containing a nano-crystalline or amorphous soft-magnetic metal alloy having a high permeability. The thickness of each metal layer is between 15 ?m and 100 ?m and the layers are placed on top of each other in such a way that the flow of current from one metal layer to another adjacent layer is made more difficult.
