1. A radiating system for a vehicle comprising:

  • a) a first conductive plate and a second conductive plate arranged substantially parallel to each other at a predetermined distance;

    b) a millimeter wave integrated circuit (MMIC) section, said MMIC section comprising;

    a first non-radiative dielectric (NRD) waveguide comprising a first dielectric strip line having a length direction, in combination with said first conductive plate and said second conductive plate; and

    an electrical element connected to said first non-radiative dielectric waveguide for generating a millimeter wave signal to be propagated therein; and

    c) a plane antenna section comprising;

    a slot antenna; and

    a second non-radiative dielectric (NRD) waveguide comprising a second dielectric strip line having a length direction, in combination with said first conductive plate, and said second conductive plate, wherein said second non-radiative dielectric waveguide is coupled in an electromagnetic coupling arrangement with said first non-radiative dielectric waveguide;

    wherein said radiating system is disposed on a supporting portion of said vehicle, said supporting portion being made of a material that allows transmission of millimeter waves with a low loss;

    wherein the plane antenna section has a deflecting portion for deflecting a leaking and radiating millimeter wave in a direction perpendicular to the length direction of said second non-radiative dielectric waveguide; and

    wherein said deflecting portion has a saw-tooth surface on a side thereof facing said second NRD waveguide and has a substantially flat surface on a side thereof facing away from said second NRD waveguide.
