Abstract
The present invention relates to a mobile transmission antenna ( ) for vehicles that comprises a monopole ( ) having a reflector ( ) 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 ( ), so that said reflector ( ) is directed towards the inside of the vehicle as seen from the monopole ( ). 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 ( ) is integrated with a device intended for other purposes, mainly with the third stoplight ( ) mounted on the rear window ( ) of the vehicle.
