Abstract
LF antennas are mounted respectively on the corners of a rear bumper of a vehicle. Radio waves radiated from the LF antennas mounted respectively on the corners of the rear bumper are propagated to the both surfaces of the vehicle on the opposite sides of the corner, providing effective transmission ranges. The remaining LF antennas are mounted respectively on the side surfaces of the vehicle such that their effective transmission ranges overlap the effective transmission ranges of the LF antennas mounted respectively on the corners of the rear bumper.
