Antenna for motor vehicles, and motor vehicle comprising such an antenna

An antenna for a motor vehicle, comprising at least:

• a mounting base configured to be connected to a mounting surface of said motor vehicle;
• an electronic circuit suitable for being arranged on said mounting base;
• a first non-resonant radiating element which is operatively connected to said electronic circuit and is configured to receive and transmit toward said electronic circuit, first signals emitted in a first frequency band by one or more devices external to the antenna;
• a second radiating element which is configured to receive and transmit toward said electronic circuit, second signals emitted in a second frequency band different from said first frequency band by one or more devices external to the antenna, said second radiating element comprising a first printed circuit board,
• wherein said first printed circuit board has a first end portion arranged on said electronic circuit and rises upwardly therefrom,
• wherein an electrically conductive track is arranged along said first printed-circuit board,
• wherein said electrically conductive track has one end connected to said electronic circuit and develops on said first printed circuit board along a substantially helical or serpentine path, up to a predetermined height;
• and
• wherein said electronic circuit is configured at least to process distinctly with each other said first and second signals received from said first non-resonant radiating element and said second radiating element;
• and
• wherein said first non-resonant radiating element comprises a shaped body that has at least a first portion having a substantially planar development which is connected at a first end thereof to said electronic circuit and rises upwardly therefrom, and a second portion which, when viewed frontally, comprises a first part extending transversely from a second end of said first portion opposite said first end, a first arm which raises from said first part away from the mounting base, a second part extending transversely from said first arm, and a second arm which extends from said second part toward the mounting base, said first and second arms extending from said second part from opposite sides of said first portion diverging from each other.
