Abstract:
1. An antenna device comprising: a substrate; a metal chassis disposed adjacent a rear surface of the substrate; a plurality of patch antenna elements formed in an array on at least a front surface of the substrate; feeding lines formed on the front surface of the substrate and through which electricity is fed to the plurality of patch antenna elements; and a ground conductor formed on the rear surface of the substrate in a portion opposite the feeding lines, wherein the substrate has a rectangular shape, wherein the plurality of patch antenna elements are formed in a middle portion of the substrate in a short side direction of the substrate and arranged in a long side direction of the substrate, and wherein the feeding lines are disposed in two side portions of the substrate in the short side direction of the substrate so as to extend in the long side direction of the substrate, the feeding lines branching such that the electricity is fed to the plurality of patch antenna elements, wherein the ground conductor includes ground patterns formed on the two side portions of the substrate in the short side direction so as to be spaced apart from each other.
