Device and method for combined signal transmission or for combined signal transmission and energy transmission

A device for combined signal transmission or for combined signal and energy transmission, the device comprising:

• at least one winding structure for generating a first electromagnetic field for transmitting energy or for transmitting signals, said at least one winding structure having a central axis being a symmetrical axis of said winding structure;
• at least one antenna structure for transmitting further signals, said antenna structure having a first part structure and a second part structure, said first part structure being disposed opposite said second part structure such that signals can be received and transmitted in a first frequency range by way of said at least one antenna structure;
• said at least one antenna structure having at least one further part structure opposite said second part structure disposed such that signals can be received and transmitted in a second frequency range by way of said antenna structure;
• wherein said first part structure is arranged adjacent said at least one winding structure in a projection plane that is oriented perpendicular to said central axis of said at least one winding structure, said further part structure is disposed adjacent said at least one winding structure in the projection plane, and said first and further part structures are arranged to form a symmetrical antenna structure;
• a damping structure for damping the first electromagnetic field, said damping structure overlapping at least in part said at least one winding structure in the projection plane;
• and
• a conductor track configured for supplying a signal to said first part structure and said further part structure in an asymmetrical matter.
