摘要:
A windshield has a generally upright transparent panel, an array of horizontal and generally parallel heater conductors on the panel and having opposite ends, and respective conductive busses connected to the heater conductors at the opposite ends thereof. Thus electricity can be applied to the busses to pass current through the heater conductors and thereby heat the panel at the array. A pair of generally upright, generally parallel, and horizontally spaced antenna conductors on the panel extend across and connect at crossing locations to the heater conductors and an output conductor is connected electrically to the antenna conductors so that radio-frequency output is taken off the output conductor. The crossing locations of each of the antenna conductors are all located at points of the same potential on the respective heater conductors and the only direct electrical connection between the pair of antenna conductors is through the heater conductors. The output conductor can be connected to one of the heater conductors and therethrough to the antenna conductors. It can also be connected directly to one of the antenna conductors and indirectly via a nonresistive impedance to the other antenna conductor. This nonresistive impedance can be a capacitor or an inductor. It is also possible to connect both the antenna conductors via such a nonresistive impedance to the output conductor.

A motor vehicle, especially a passenger vehicle, has a metallic body provided with a window opening receiving an antenna window. The antenna window has inner and outer panes bonded together by a bonding layer with an optically-transparent electrically-conductive solar central coating reducing transmission in at least a part of the solar energy range. At least one edge of the window is left free from the coating and in this region a slot antenna is formed. At least at one additional edge, the coating runs to that edge and is overlapped by the framing portion of the vehicle body and is coupled with a high-frequency coupling to the coating.

A method of manufacturing a glazing having a frequency selective surface comprising the steps of:a) depositing a coating on a substrate, said coating being non-transmitting to radio frequency (RF) radiation;b) providing a laser beam andc) removing a portion of the coating by laser ablation to form one or more curves and/or lines having a spacing selected to provide transparency of the coating to RF radiation of a desired wavelength;characterized byd) directing the laser beam and/or moving the substrate such that the relative motion of the intersection of the laser beam and the coating, with respect to the substrate, comprises motion in a first dimension, wherein said motion is simultaneously superimposed with a reciprocating motion in a second dimension; e) translating said intersection in the second dimension; and f) repeating at least step d) out of steps d) to f).
摘要:
Laminated vehicle glazing with a conductive panel defining slot antennas between the conductive panel and the metal surround of the vehicle with connecting leads, and a camera or other device in an area where the device and the antenna do not overlap. Locating the device in a different position to the slot antenna reduces the electromagnetic interference that the slot antenna experiences and prevents malfunction of the device where the slot antenna is used to transmit radio signals.

An automotive glazing having a non-galvanic contact for an electrical device associated with the glazing is disclosed. The glazing comprises a first ply and a second ply of transparent glazing material having a ply of interlayer material extending between the plies of glazing material. The glazing also comprises an electric circuit, having a first connector portion, situated adjacent the ply of interlayer material, the first connector portion being configured to form a coupling region such that electrical signals in the circuit are can be coupled between the coupling region and an electrical device placed on the glazing. A second connector portion is included on the surface of the second ply of glazing material situated away from the interlayer material, and connectable to an electrical device. The second connector portion is adapted to receive a ferromagnetic core. This leads to an increased coupling factor (efficiency), making the connection suitable for powering a variety of electrical devices used within automotive vehicles and conventionally mounted on glazings.
