<p>An antenna pattern is formed on the surface an antenna element (14) of a module (11), and the antenna element (14) comes into contact with the flat surface of a hemispherical lens (13) at the bottom surface. A mounting element (15) is provided with an aperture (15C), a rectangular recess (15B), and a circular recess (15A), and the aperture (15C) exposes the antenna pattern. The rectangular recess (15B) is provided with the aperture (15C) at the bottom of the recess, comes into contact with the sides of the antenna element (14) at the sides of the recess, and positions the antenna element (14). The circular recess (15A) is provided with the rectangular recess (15B) at the bottom of the recess, comes into contact with the hemispherical lens (13) at the sides of the recess, and positions the lens (13). A fixing cover (12) comes into contact with the spherical surface of the hemispherical lens (13), thereby holding the antenna element (14) and the lens (13) between the mounting element (15) and the fixing cover (12).</p> |
