Transmitting Antenna Arrangement For Emitting A Longwave Wake-Up Signal For An Id Transmitter In A Keyless Motor Vehicle Access System |
摘要 |
A transmitting antenna arrangement for emitting a longwave wake-up signal for an ID transmitter in a keyless motor vehicle system includes an induction coil. The coil includes at least one winding and a core surrounded by the winding is arranged inside a component of the motor vehicle. The core is shaped as a flat strip and includes 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 mum and 100 mum 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. |
