Abstract
The invention relates to a rearview mirror device for vehicles incorporating a radio-frequency reception system. The rearview mirror device comprises: a light-reflective surface made of an electrically conductive material, and at least one planar conductive element lying on a plane substantially parallel to said reflective surface. The light-reflective surface and said conductive element are capacitively coupled and are used in combination for the reception of radio-frequency signals. The invention provides a rearview mirror with great simplicity and very-low cost.
Claims15
A rearview mirror device integrating a radio-frequency reception system, said device comprising:
- a light-reflective surface made of an electrically conductive material,
- at least one planar conductive element lying on a plane substantially parallel to said reflective surface, wherein the distance between the reflective surface and said conductive element is selected in order to have the reflective surface and said conductive element capacitively coupled and to define a selected capacitance value suitable for the reception of radio-frequency signals.
