Abstract
An antenna arrangement for the mobile communication of a rail vehicle and a rail vehicle with an antenna arrangement of the type. The antenna arrangement has at least two transmitting antennas and at least two receiving antennas. The transmitting antennas are spatially grouped in a transmitting group and the receiving antennas are spatially grouped in a receiving group. The distances between the transmitting antennas and between the receiving antennas is smaller than the overall distance between the transmitting group and the receiving group. The antennas can thereby be arranged in a much more space-saving fashion on the vehicles because large distances have to be provided only between the groups, not between the antennas within the groups. Where the space needed is low, interference-free operation of the antennas is thus advantageously possible.
