First Claim
Patent Images
1. An antenna structure assembly for enabling radio communication of a first motor vehicle with at least one other motor vehicle, and for transmitting and receiving useful communication signals, comprising:
- an antenna structure mounted to the first motor vehicle, said antenna structure having a main lobe;
a controller connected to said antenna structure and having an input for receiving from a speed recording device of the motor vehicle a signal representing a travel speed of the motor vehicle, said controller being configured to control said antenna structure to selectively change a setting of said main lobe, said controller adjusting a beam spread angle of said main lobe of said antenna structure in dependence on a travel speed of the first motor vehicle.

Abstract
A motor vehicle is equipped for radio communication with at least one further motor vehicle. An antenna structure is used to transmit and receive useful signals. The antenna structure can be controlled with the aid of a control device in such a way that it is possible to change the setting of the main lobe of the antenna. A method is also disclosed for operating an antenna structure which is installed in a motor vehicle.

8. A motor vehicle equipped for radio communication with at least one other motor vehicle, comprising:
-
an antenna structure for transmitting and receiving useful radio communication signals, said antenna structure having a main lobe; and a controller connected to said antenna structure and configured to continuously change a direction angle of said main lobe of said antenna structure for establishing a communication connection to the other motor vehicle, said controller receiving a signal from a speed recording device indicating a speed of the motor vehicle and reducing a maximum angle of deflection for the direction of said main lobe of said antenna structure with increasing vehicle speed. - View Dependent Claims (9)
