Abstract

An antenna window (1) with a high-frequency electric component (HF) placed fixedly on one of its surfaces, which is electrically connected to a conductor structure (3) provided on the same surface of the window, characterized in that the high-frequency component (HF) has at least one flat coupling electrode (5), which is kept at a specific distance from the flat conductor structure (3) conducting high-frequency antenna signals, by means of an intermediate dielectric layer (4), in order to form said electrical connection.

Claims

1. An antenna window (1) with a high-frequency electric component (HF) placed fixedly on one of its surfaces, which is electrically connected to a conductor structure (3) provided on the same surface of the window, characterized in that the high-frequency component (HF) has at least one flat coupling electrode (5), which is kept at a specific distance from the flat conductor structure (3) conducting high-frequency antenna signals, by means of an intermediate dielectric layer (4), in order to form said electrical connection.

2. The antenna window as claimed in claim 1, characterized in that the high-frequency component (HF) comprises a support plate (7) supporting the flat coupling electrode (5) together with other components connected thereto.

3. The antenna window as claimed in claim 1 or 2, characterized in that the intermediate dielectric layer is formed by adhesive tape (4) of a specific thickness.

4. The antenna window as claimed in claim 1 or 2, characterized in that the intermediate dielectric layer is a layer of air with a specific thickness.

5. The antenna window as claimed in any one of the preceding claims, characterized in that the high-frequency component (HF) fastened to the window (1) is overmolded, hermetically against air and water vapor, by means of a cured compound (10) bonding to the surface of the window.

6. The antenna window as claimed in any one of the preceding claims, characterized in that the flat conductor structure (3) consists of an electrically conducting paste to be baked, which is printed and baked on one surface of the window (1).

7. The antenna window as claimed in any one of the preceding claims, characterized in that the antenna elements also consist of an electrically conducting paste to be baked, which is printed and baked.

8. The antenna window as claimed in any one of the preceding claims, characterized in that the flat conductor structure is connected, in an electric or capacitive manner, to antenna elements which are placed on another surface of the window, in particular inside a laminated window.

9. The antenna window as claimed in any one of the preceding claims, characterized in that the flat conductor structure is divided into several parts conducting signals, which parts are distant and electrically separated from each other, with which a specific coupling electrode of the high-frequency component is individually spatially and functionally combined.
