摘要

An antenna intended to be loaded on a rail vehicle hired to track down this veu00eccu rail it along a rail equipped with a system of beacons on the ground. The invention relates to an antenna (2) to be loaded on a rail vehicle (V), to locate the rail vehicle along a rail (VF) equipped with a system of buoys (1) in the soil.The antenna is capable of capturing an electromagnetic signal representative of information emitted by the beacon, when it is crossed by the railway vehicle, and it comprises a first circuit receiver in the form of a plain ring (a) and a second circuit receiver in the form of a ring of two spirit Ras in 8 (b).The antenna includes, in addition, a third receiver circuit (c) in the form of a ring with three coils with a coil median (C2) arranged between two external coils (C1, C3), the first, second and third circuits receptu00f3res being superimposed.The three circuits receptor - res featuring all about a same axis of symmetry longitudinal (x) and substantially the same transverse axis of symmetry (y).
