Transparent, flat antenna, suitable for transmitting and receiving electromagnetic waves, method for the production thereof, and use thereof

摘要

A transparent, flat antenna for transmitting and receiving electromagnetic waves is described. The transparent, flat antenna comprises a transparent, electrically insulating substrate with a transparent, electrically conductive coating. Methods to produce such a transparent, flat antenna are also described.

主权项

1. A transparent, flat antenna for transmitting and receiving electromagnetic waves, comprising
a) at least one first transparent electrically insulating substrate, wherein a surface of the at least one first transparent electrically insulating substrate comprises an electrically insulating circumferential edge region; b) a transparent electrically conductive coating, wherein:
b1) the transparent electrically conductive coating covers large areas of the surface of the at least one first transparent electrically insulating substrate up to the electrically insulating circumferential edge region, andb2) the transparent electrically conductive coating is formed by at least two flat segments, wherein:
i) the at least two flat segments contain at least one electrically conductive material,ii) the at least two flat segments are insulated from each other by at least one linear electrically insulating region, andiii) at least one flat segment in the at least two flat segments is subdivided by linear electrically insulating regions; c) at least one connection for decoupling of the received electromagnetic waves from the at least one flat segment; and d) at least one second transparent electrically insulating substrate and at least one transparent tear-resistant adhesive layer located between the at least one first transparent electrically insulating substrate and the at least one second transparent electrically insulating substrate.
