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] Attention should first be drawn to FIGS. 1 and 2A to 2D , in which a hybrid antenna configuration, generally designated by reference numeral 1 , and an antenna arrangement 100 comprising this antenna configuration 1 are shown as a first embodiment of the invention. The hybrid antenna structure 1 is embodied here, for example, as a transparent composite foil 20 , which is only partially shown in FIG. 1 . The composite sheet 20 is transparent to visible light such as in the wavelength range of 350nm to 800nm, wherein the concept "transparent" should be understood as a light transmittance greater than 50%, preferably greater than 75%, and especially preferably greater than 80%. Rate. The composite sheet 20 is used, for example, as a windshield of a motor vehicle, but it can also be used there.
[0044] The composite sheet 20 consists of two transparent individual sheets, namely a rigid outer sheet 2 and a rigid inner sheet 3 , which are fixedly connected to each other by ...

The invention relates to an antenna assembly, comprising at least one insulating substrate, at least one conductive coating, which covers at least some sections of a surface of the substrate and is used at least in some sections as a flat top antenna for receiving electromagnetic waves, at least one first coupling electrode which is electrically coupled to the conductive coating for extracting data signals from the flat top antenna, at least one source of interference, which is disposed such that interfering signals can be received by the flat top antenna, a structure which serves as a ground and which is electrically conductive, and at least one second coupling electrode which is electrically coupled to the conductive coating for extracting interfering signals that are received by the flat top antenna from the flat top antenna.; The at least one second coupling electrode comprises a first coupling surface, and the conductive structure comprises a second coupling surface that is capacitively coupled to the first coupling surface, wherein the two coupling surfaces are designed such that they selectively allow the transmission of a frequency range that corresponds to the interfering signals to be extracted from the flat top antenna.
Description
technical field [0001] The invention relates to an antenna arrangement and an antenna construction with a planar antenna for receiving electromagnetic waves, as well as a method for operating the antenna arrangement. Background technique [0002] Substrates with electrically conductive coatings have been described several times in the patent literature. For this, reference is made, for example, only to documents DE 19858227 C1, DE 10200705286, DE 102008018147 A1 and DE 102008029986 A1. The electrically conductive coating is generally used to reflect heat radiation and thus to improve thermal comfort, for example in automobiles or in buildings. It is often also used as a heating layer for full-area electrical heating of transparent sheets. [0003] As disclosed in documents DE 10106125 A1, DE 0319606 A1, EP 0720249 A2, US 2003 / 0112190 A1 and DE 19843338 C2, transparent coatings can also be used as surface antennas for receiving electromagnetic waves due to their electrical ...
