Abstract: The present invention comprises a device for the reception and transmission of electromagnetic waves, the device being well suited for very complex radiation diagrams while remaining within predefined transmission power levels. This is effected by an antenna structure and a driver logic circuit which are provided for the transmitting elements in such a way that an individually presettable directional and/or angular limitation of the basic transmitting power to maximally permitted transmitting powers in selectable directions and in particular in selectable solid angles is provided. Accordingly, the radiated transmitting power for determined directions and/or determined solid angles deviates downwards from the normal in the remaining directions and/or solid angles radiated basic transmitting power.
