Problems solved by technology
However, it is difficult to implement this method in practice
On the one hand, the suppression and shielding of sources of interference is technically complex and is associated with relatively high costs
On the other hand, for example in the case of front-mounted engines and surface antennas mounted on the windshield, it is generally not possible to maintain a correspondingly large spatial distance between the source of interference and the surface antenna
In modern vehicles it is difficult to always arrange electrical equipment in the area of the base point of the interior rearview mirror, which electrical equipment can form a source of interference for the surface antenna of the windshield

Embodiment Construction
[0043] Pay attention first figure 1 and Figures 2A to 2D , wherein a hybrid antenna configuration generally designated by reference numeral 1 and an antenna configuration 100 including this antenna configuration 1 are shown as a first embodiment of the present invention. The hybrid antenna arrangement 1 is embodied here, for example, as a transparent composite sheet 20 , which is figure 1 is only partially shown. The composite sheet 20 is transparent to visible light, for example in the wavelength range from 350 nm to 800 nm, wherein the term "transparent" is understood to mean a light transmission with a light transmission of more than 50%, preferably more than 75% and particularly preferably more than 80% Rate. The composite sheet 20 is used, for example, as a windshield for automobiles, but it can also be used elsewhere.
[0044] The composite sheet 20 comprises two transparent individual sheets, namely a rigid outer sheet 2 and a rigid inner sheet 3 , which are fixedl...

The arrangement (100) has a coupling electrode (36, 36') electrically coupled to a conductive coating (6) for extracting interfering signals of interference sources (39, 39') from a flat top antenna. The electrode comprises coupling surfaces (40, 40'), and a conductive structure comprises another coupling surface that is capacitively coupled to the former coupling surfaces. The coupling surfaces are designed such that the coupling surfaces selectively allow transmission of a frequency range that corresponds to the interfering signals to be extracted from the flat top antenna. An independent claim is also included for a method for operating an antenna arrangement.
Description
technical field [0001] The present invention relates to an antenna configuration and an antenna configuration having a surface antenna for receiving electromagnetic waves, and a method for driving the antenna configuration. Background technique [0002] Substrates with conductive coatings have been described several times in the patent literature. For this, reference is only necessary to the documents DE 19858227 C1, DE 10200705286, DE 102008018147 A1 and DE 102008029986 A1, for example. The conductive coating is often used to reflect thermal radiation and thus to improve thermal comfort, for example in automobiles or in buildings. It is also often used as a heating layer to provide full-plane electrical heating of the transparent sheet. [0003] As disclosed in documents DE 10106125 A1, DE 0319606 A1, EP 0720249 A2, US 2003 / 0112190 A1 and DE 19843338 C2, the transparent coating can also be used as a surface antenna for receiving electromagnetic waves due to its electrical...
