Vehicle window glass

Abstract

To provide a vehicle window glass which can mount an antenna, capable of receiving a plurality of media, in a narrow region.SOLUTION: The vehicle window glass includes: a glass plate; a first power supply part disposed on the glass plate; and a mixing antenna element disposed on the glass plate and extending from the first power supply part. The mixing antenna element includes: an element for a first medium which mainly receives a frequency band of the first medium; and an element for a second medium which mainly receives a frequency band of the second medium, which has a higher frequency band than that of the first medium.SELECTED DRAWING: Figure 1

Claims

1. A glass plate and A defogger having multiple horizontal heating wires is placed on the glass plate, The glass plate includes a first power supply unit positioned above the defogger, The glass plate includes a second power supply unit positioned above the defogger, The glass plate is positioned above the defogger and includes a mixed antenna element extending from the first power supply unit, The glass plate includes a first media antenna element positioned above the defogger, extending from the second power supply unit, and receiving the frequency band of the first media; Equipped with, The aforementioned mixing antenna button is A first media element that primarily receives the frequency band of the first media, A second media element that primarily receives the frequency band of a second media having a higher frequency band than the first media, and at least a portion of it extends vertically, Equipped with, The defogger and the first media element of the mixed antenna element are capacitively coupled. The defogger and the first media antenna element are capacitively coupled. A vehicle window glass in which the first medium is FM broadcasting and the second medium is DAB broadcasting.

2. The vehicle window glass according to claim 1, wherein the mixed antenna element further comprises a cancellation element between the first media element and the second media element for blocking or attenuating the received signal in the frequency band of the second media.

3. Further comprising an extension element extending from the defogger, The vehicle window glass according to claim 1 or 2, wherein at least a portion of the first media element extends parallel to the extension element.

4. Further comprising an extension element extending from the defogger, The vehicle window glass according to claim 1 or 2, wherein at least a portion of the first media element is in close proximity to the extension element.

5. The vehicle window glass according to claim 4, wherein the extension element is brought close to the first media element of the mixed antenna element, thereby capacitively coupling the first media element and the extension element.

6. The vehicle window glass according to claim 4 or 5, wherein at least a portion of the first media element extends parallel to the extension element.

7. The vehicle window glass according to claim 6, wherein the length of the portion of the first media element parallel to the extension element is 200 mm or less.
