Abstract:
1. A radio wave transmission/reception device for vehicles, comprising: a radio wave transmission/reception unit; a radio wave reflection unit installed at a predetermined location near the radio wave transmission/reception unit and changing directions of radio waves transmitted from the radio wave transmission/reception unit such that the radio waves can be propagated forwards from a vehicle; a radio wave rectilinear propagation guide unit installed in front of the radio wave reflection unit and guiding rectilinear propagation of transmitted/received radio waves; and a viewing window installed in front of the radio wave rectilinear propagation guide unit and oriented toward a radiator grille of the vehicle; wherein the radio wave rectilinear propagation guide unit is provided with an inductive film parallel to the viewing window, with at least a reflection protrusion formed on a surface of the inductive film facing the viewing window.
