ATC ANTENNA DEVICE, ATC SIGNAL TRANSMISSION DEVICE AND VEHICLE

An ATC antenna device (100) provided on a body (1) of a lead car to receive signals from outside. In the ATC antenna device (100), a pair of ATC antenna coils (4a, 4b) is disposed symmetrically with respect to a center line (AX) of the body (1) as viewed in a traveling direction of the body (1), and the paired ATC antenna coils (4a, 4b) are connected in series and are of opposite phase. An ATC antenna support device (2) is attached to the body (1) to support the paired ATC antenna coils (4a, 4b), and is disposed asymmetrically with respect to the center line (AX).
