Abstract: An antenna array for a motor vehicle includes at least one AM antenna for receiving long wave, medium wave and/or short wave signals as well as at least one additional electrically conductive structural part that is arranged so as to be adjacent to the AM antenna. The additional structural part is connected to a ground potential and/or supply potential of the motor vehicle by at least one filter element, by which the signal frequencies in at least one frequency range that is to be received by the AM antenna are suppressed.

Abstract: An antenna configuration is provided for radio reception in motor vehicles, the roof region of which is made predominantly of dielectric materials, and for motor vehicles having roof structures that can be collapsed for open driving operation. The antenna configuration includes a combination of emitters that are integrated into elements of the roof region, with emitters that are disposed in cavities of the interior paneling essentially below the belt line of the vehicle. A ground connection is provided for emitters that are disposed in a roof structure having movable elements by way of at least one resilient contact between movable metal components of the roof structure and the metal car body. Also included is a switching system for alternating operation of the emitters.
