Vehicle window antenna with antenna elements on two surfaces
First Claim
1. A vehicle window antenna comprising:
- a laminated glass for use in a vehicle having inner and outer glasses facing respectively the interior and exterior of the vehicle, and an intermediate layer sandwiched therebetween;
heating conductor means mounted on a first surface of said laminated glass which is selected from all surfaces thereof but the outer surface of said outer glass exposed to the exterior of the vehicle;
first antenna conductor means mounted on a second surface of said laminated glass which is different from said first surface and said outer surface of said outer glass; and
second antenna conductor means mounted on the same surface of said laminated glass as said heating conductor means.

Abstract
The disclosure is directed to a vehicle window equipped with a radio antenna as well as a heating defroster. A laminated window glass is employed advantageously which comprises inner and outer plates of glass facing respectively the interior and exterior of the vehicle. The heating structure is mounted on a first surface of the laminated glass. At least part of the antenna elements is formed on a second surface which is different from the first surface supporting the heater elements. The antenna bearing surface and/or heater bearing surface may be any surface of the laminated glass; the outer surface of the outer glass plate should be excluded from the supporting surface, however, because such surface is exposed to the exterior of the vehicle. Therefore, a relatively large area is always available for the antenna structure irrespective of the size of the window. It becomes more flexible and easier to make the design of antenna having the desired characteristics.
