Abstract: Flat-top antenna emitting and/or receiving an electromagnetic field, particularly for a motor vehicle, formed of multi-strand conductors connected one by one to form turns. The flat-top antenna is positioned on a mechanical support so that it is mainly at right angles to the surface defined by the turns. Hands-free access and starting system may comprise such an antenna.

Abstract: The communication facility for system for low frequency communication by electromagnetic coupling, comprises at least one electromagnetic field transmitting and/or receiving antenna in the form of a coil (2) disposed on a substrate board (1) serving as support, this board having a certain thickness. The coil has turns which are wound in the thickness of the substrate board so that the sensitivity of the antenna can be improved without increasing the thickness of the communication facility.
