<p>A patch antenna is provided with a metallic wall (1); a patch conductor (4) formed on a printed board (2), i.e., a dielectric substrate, by etching or the like; and a power feeding means for the patch conductor. The metallic wall (1) is bent forward along the both side surfaces of the printed board (2). The metallic wall (1) is inclined inward, and an interval between the both end portions is smaller than a radiation aperture dimension of the patch antenna when viewed from an antenna radiation direction. With such configuration, a directional beam width can be widened, and the directional beam width on a surface parallel to the polarization surface of linearly-polarized wave and the directional beam width on a surface orthogonally intersecting with the polarization surface of the linearly-polarized wave are accorded with each other.</p> |
