The invention discloses a transponder with an expanded range of action. The transponder comprises a signal processing module, a coaxial cable and a housing. The core wire and the shielding layer of the coaxial cable of the transponder serve as a transmitting antenna and a receiving antenna of the transponder, respectively, and the length of the coaxial cable in a track direction is greater than the length of the transponder in a sleeper direction; the horizontal range of action of the transponder is extended, so that a train is still within the horizontal range of action of the transponder after moving by a braking distance at parking, and when the trains starts, message information still can be effectively obtained from the transponder.
