<p>PROBLEM TO BE SOLVED: To provide a structure for a radar system that can form a desired antenna pattern which is low cost and light-weight. SOLUTION: This radar system is provided with a cover 6 of nearly a box shape with a bottom made of a dielectric material, such as a ceramic or a plastic and with nearly a flat base plate 5 made of a dielectric material. A metal film 6a is formed to a bottom in the cover 6, except for a part 6aa acting as an antenna pattern, a metal film 5a is formed to an upper side of the base 5, a dielectric plate 1 of nearly a flat plate shape mode of a dielectric material is fitted to the upper part of the metal film 5a and a feeding plate 2 is provided in an upper part of the dielectric plate 1 to form a slot antenna.</p> |
