| 摘要 |
The present invention relates to an antenna assembly, comprising an outer module (1) including at least one antenna radiator (16, 17) fixed to an electrically conductive base (15), comprising at least one base plate. This base constitutes a first part of a coupling capacitance transferring the RF-signal through a dielectric pane. A connection unit (20, 30) interacting with the base (15) is mounted on the inside of the pane directly opposite the base. A coaxial cable (6) from the vehicle's radio or communication apparatus is connected to this unit (20, 30), which comprises a box (14) of at least partially electrically conductive material, having at least two plates (10, 12) facing towards the pane, where a first plate (10) in series with a first connection conductor (9) is tuned for a first frequency band and a second plate (12) in series with a second connection conductor (11) is tuned for a second frequency band. The other end of the connection conductors are attached to the coaxial cable (6). |
