An antenna assembly including: an insulating substrate; a conductive coating covering a surface of the substrate at least section-wise and serving at least section-wise as a planar antenna receiving electromagnetic waves; a first coupling electrode electrically coupled to the conductive coating extracting useful signals from the planar antenna; a source of interference disposed such that interfering signals can be received by the planar antenna; an electrically conductive ground; and a second coupling electrode electrically coupled to the conductive coating coupling out interfering signals received by the planar antenna from the planar antenna. The second coupling electrode includes a first coupling surface and the conductive structure includes a second coupling surface capacitively coupled to the first coupling surface, the two coupling surfaces configured to selectively allow passage of a frequency range corresponding to the interfering signals to be extracted from the planar antenna.

Antenna assembly and antenna structure with improved signal-to-noise ratio

A panel heater with at least one flat substrate and an electrically conductive coating is described. The electrically conductive coating extends at least over part of a substrate area and is electrically connected to at least two connecting electrodes provided for electrical connection to the two terminals of a voltage source, such that by applying a feed voltage, a heating current flows in a heating field, which is provided with one or a plurality of heating current paths formed into the conductive coating. The panel heater has one or more measurement current paths formed into the electrically conductive coating, which differ at least in sections from the heating current paths. The heating and measurement current paths are formed into the electrically conductive coating by coating-free separating regions. A method for operation and use of the panel heater is also described.

Panel heater with temperature monitoring

The invention relates to a hybrid antenna structure that comprises at least one electrically insulating substrate, at least one electrically conductive coating that covers at least one surface of the substrate at least section-wise and serves as a planar antenna for reception of electromagnetic waves, as well as at least one coupling electrode electrically coupled to the conductive coating for coupling out of antenna signals from the planar antenna. It is essential here that the coupling electrode be electrically coupled to an unshielded, linear antenna conductor that serves as a linear antenna for reception of electromagnetic waves, with the antenna conductor situated outside an area that can be projected by orthogonal parallel projection onto the planar antenna serving as a projection area, by which means an antenna foot point of the linear antenna becomes a common antenna foot point of the linear and planar antenna. The invention further relates to a method for producing such a hybrid antenna structure.

Antenna bandwidth-optimized by hybrid structure comprising planar and linear emitters

The invention relates to a transparent pane with a transparent heatable coating, which extends at least over a part of the pane surface, in particular over its visual field. The heatable coating is divided by at least one heatable coating-free zone into at least one first heatable coating zone and a second heatable coating zone, wherein the two heatable coating zones are in each case electrically connected to at least two collecting conductors such that after application of a supply voltage that is provided by a voltage source, in each case a current flows over at least one first heating field formed by the first heatable coating zone and at least one second heating field formed by the second heatable coating zone. At least one heating element is disposed in the heatable coating-free zone, which heating element has an ohmic resistance such that by means of application of the supply voltage to the heating element, the pane is heatable in a surface area containing the heatable coating-free zone. The at least one heating element is configured such that by means of application of the supply voltage to the heating element, the pane is also heatable in at least one surface area adjacent the coating-free zone which surface area contains at least one of the collecting conductors.

A pane with electrically conductive structures is described. The pane has at least two electrically conductive structures galvanically separated from each other, a galvanic separating layer on at least on one of the electrically conductive structures, and an electrical conductor on the galvanic separating layer. The galvanic separating layer galvanically separates the conductor from at least one of the structures. A method for producing the pane and a use of the same are also described.

An antenna arrangement for transmitting and receiving electromagnetic signals includes a flat carrier substrate made of a dielectric material, a first conducting track applied to a surface of the carrier substrate, a second conducting track applied to an other surface of the carrier substrate. The first conducting track includes at one end a point of contact to gather or inject signals and a first dipole at the opposite end. The second conducting track includes at one end a point of contact to gather or inject the signals and a second dipole at the opposite end. The first and the second dipoles form a crossed dipole. The antenna arrangement may be disposed on a glazing.
