Abstract
A transmission device for a motor vehicle for transmitting a radio signal is provided. A coil antenna is provided for emitting the radio signal, and an electric driver circuit is designed to generate an electric alternating current with a specified transmission frequency in the coil antenna. The coil antenna is arranged on at least one support element, and a parasitic parallel capacitance acting parallel to an intrinsic inductance of the coil antenna is produced by virtue of the geometry and/or the material of the at least one support element and/or by virtue of the shape of the coil antenna, the parasitic parallel capacitance together with the intrinsic inductance functioning as a parallel resonant circuit with a specified intrinsic resonant frequency with respect to the driver circuit.
