Abstract
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.
Claims21
A laminated vehicle glazing for fitting within a metal surround, said glazing comprising:
- an inner pane,
- an outer pane,
- a bonding layer between said inner pane and said outer pane,
- a conductive panel arranged to define at least one elongated dielectric slot antenna between an edge of the metal surround and an edge of the conductive panel, said at least one slot antenna comprising a high-frequency current-conductive frame bounding an elongated area of the antenna and opposed edge conductors adapted for the connection of connecting leads, and
- at least one device that can emit electromagnetic radiation, wherein said device occupies an area,
- wherein the area of the at least one device that can emit electromagnetic radiation and the area of the at least one slot antenna do not overlap in the projection of said areas on the plane of the outer pane.
