Abstract (en)
The invention relates to an antenna arrangement, in particular an antenna arrangement (7, 7a) of a rail vehicle (1) for receiving signals (10) transmitted by a track-sided transmitter (9), and a method for determining an absolute speed of a rail vehicle (1), wherein the antenna arrangement (7, 7a) is mounted on a rail vehicle (1), wherein the antenna arrangement (7, 7a) comprises a first antenna element (11, 11 a) and at least another antenna element (12, 12a) for receiving a signal (10) transmitted by the track-sided transmitter (9), and wherein the first and the other antenna element (11, 11a, 12, 12a) are designed as separate antenna elements (11, 11 a, 12, 12a), wherein the first and the other antenna element (11, 11 a, 12, 12a) are arranged with a predetermined displacement (A) along a direction of travel of the rail vehicle (1).
