ANTENNA ASSEMBLY AND ANTENNA DESIGN HAVING AN IMPROVED SIGNAL-TO-NOISE RATIO

摘要

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.
