| 摘要 |
<p>The present invention relates to a mobile transmission antenna (1) for vehicles that comprises a monopole (8) having a reflector (15) associated therewith. The unit thus formed is mounted on or adjacent to the inner surface of members of the vehicle which are permissive to electromagnetic waves, mainly the vehicle windows (3), so that said reflector (15) is directed towards the inside of the vehicle as seen from the monopole (8). During a transmission, this configuration reduces simply and economically to a harmless level the incident radiation of high-frequency energy that penetrates into the vehicle. The antenna is further protected from potential unauthorised handling from the outside and does not look like an radio-telephone antenna. In a particularly advantageous embodiment of the present invention, the radio-telephone antenna (1) is integrated with a device intended for other purposes, mainly with the third stoplight (4) mounted on the rear window (3) of the vehicle.</p> |
