Abstract (en)
[origin: WO9323890A1] An antenna arrangement for motor vehicles has an outer radio antenna (1) and a window pane (2) mounted in the metallic car body (3). The outer radio antenna (1) is arranged next to the window pane opening, on the car body (3) or on the window pane (2) itself. An optically transparent two-dimensional structure (4) made of a conductive material is mounted on the window pane, next to the outer radio antenna (1). This structure (4) is substantially opaque to electromagnetic radiation propagating through the window pane opening, as far as radio waves in the radio broadcasting frequency domain are concerned, and is connected with low impedance to the metallic car body (3) in the radio broadcasting frequency domain. Its dimensions are selected so that the inside of the vehicle is sufficiently shielded from the electromagnetic radiation generated by the outer antenna.
