A method for validating a vehicle-to-X message, - wherein the vehicle-to-X message comprises an absolute position of a transmitter, - wherein an absolute position of a receiver is determined on the basis of a global satellite navigation method and/or on the basis of a map comparison, - wherein a first relative position of the transmitter with respect to the receiver is calculated from the absolute position of the receiver and the absolute position of the transmitter, - wherein a comparison of the first relative position with a second relative position is performed and wherein the vehicle-to-X message is validated on detecting a most extensive correspondence of the first relative position with the second relative position, and/or the vehicle-to-X message is rejected on detecting a most extensive deviation of the first relative position from the second relative position, characterized in that - the vehicle-to-X message is received by an antenna arrangement (10, 406) having at least two antenna elements (407, 407', 407", 407"') of a vehicle-to-X communication device, - wherein an electromagnetic field strength of the vehicle-to-X message is picked up with different power densities by the at least two antenna elements (407, 407', 407", 407"') due to the different reception characteristics of the at least two antenna elements (407, 407', 407", 407"'), and - wherein at the receiver end, the second relative position of the transmitter with respect to the receiver is calculated or is read out of a reference characteristic map from the ratio of the power densities picked up by the at least two antenna elements (407, 407', 407", 407"') of the antenna arrangement (10, 406). - wherein the vehicle-to-X message comprises an absolute position of a transmitter, - wherein an absolute position of a receiver is determined on the basis of a global satellite navigation method and/or on the basis of a map comparison, - wherein a first relative position of the transmitter with respect to the receiver is calculated from the absolute position of the receiver and the absolute position of the transmitter, - wherein a comparison of the first relative position with a second relative position is performed and wherein the vehicle-to-X message is validated on detecting a most extensive correspondence of the first relative position with the second relative position, and/or the vehicle-to-X message is rejected on detecting a most extensive deviation of the first relative position from the second relative position, - the vehicle-to-X message is received by an antenna arrangement (10, 406) having at least two antenna elements (407, 407', 407", 407"') of a vehicle-to-X communication device, - wherein an electromagnetic field strength of the vehicle-to-X message is picked up with different power densities by the at least two antenna elements (407, 407', 407", 407"') due to the different reception characteristics of the at least two antenna elements (407, 407', 407", 407"'), and - wherein at the receiver end, the second relative position of the transmitter with respect to the receiver is calculated or is read out of a reference characteristic map from the ratio of the power densities picked up by the at least two antenna elements (407, 407', 407", 407"') of the antenna arrangement (10, 406).
