Abstract
Provided is a linear polarization array antenna device for vehicle that is low-cost and has a high gain, by forming an array antenna and a transmission line by conductor patterns on a substrate. The present invention is provided with: a dipole antenna array in which a plurality of dipole antennas formed by the conductor patterns provided on a dielectric substrate are arranged; and two parallel transmission lines formed by the conductor patterns provided on the dielectric substrate, wherein power is supplied to the dipole antennas via the transmission lines. The two parallel transmission lines have a structure in which a pair of conductor patterns face each other across the dielectric substrate interposed between the pair of the conductor patterns.
