Abstract

An antenna includes a plurality of transmitting antennas that are: a first transmitting antenna that transmits a transmission wave in a right-upward direction relative to a reference axis substantially parallel to a road surface; a second transmitting antenna that transmits a transmission wave in a left-upward direction relative to the reference axis; a third transmitting antenna that transmits a transmission wave in a right-downward direction relative to the reference axis; and a fourth transmitting antenna that transmits a transmission wave in a left-downward direction relative to the reference axis. A transmission range of the transmission wave transmitted from each of the first transmitting antenna, the second transmitting antenna, the third transmitting antenna and the fourth transmitting antenna partially overlaps with the transmission ranges of the transmission waves transmitted from the transmitting antennas located in vicinity.
