1 . An antenna device characterized by: comprising: a dielectric substrate having a ground plane formed on one of plate faces; a patch antenna having a dominant polarization direction in a predetermined direction of the plate faces of the dielectric substrate; at least one patch radiating element for supplying electric power provided on the patch antenna, the at least one patch radiating element being formed on a plate face on an opposite side of the plate face of the dielectric substrate on which the ground plane is formed; a patch-shaped conductor pattern formed on a substrate front face that is the plate face of the dielectric substrate on which the patch radiating element is formed; a plurality of connection conductors formed across the conductor pattern and the ground plane to penetrate the dielectric substrate for electrically connecting the conductor pattern to the ground plane; and a conductive structure having the conductor pattern and the plurality of connection conductors, wherein a plurality of the conductive structures is provided. 2 . The antenna device according to claim 1 , wherein the conductive structure has at least one group including a plurality of the connection conductors arrayed in a row; and an array direction of the plurality of connection conductors configuring the group is different from the dominant polarization direction of the patch antenna. 3 . The antenna device according to claim 2 , wherein an array direction of the plurality of connection conductors configuring the group is a direction perpendicular to the dominant polarization direction of the patch antenna. 4 . The antenna device according to claim 1 , wherein around the patch radiating element configuring the patch antenna on the substrate front face, a conductor pattern absent region is formed, the conductor pattern absent region including the patch radiating element without the conductor pattern; and the conductor pattern is formed on an outer side of the conductor pattern absent region on the substrate front face.
