PURPOSE: To reflect a radio wave from all incident angles by providing a concaved corner reflector of regular triangular pyramid by providing a concaved corner reflector of regular triangular pyramid form to each face of a regular icosahedron.
CONSTITUTION: The corner reflector 1 is formed into a concaved form of a regular triangular pyramid made by cutting the regular hexahedron with a plane passing through three apexes B, C, D adjacent to one apex A of the regular hexahedron having a side (a) each. Twenty sets of the corner reflectors 1 of the concaved form are provided and arranged so that each aperture 1a of the corner reflector 1 is faced outward at each of the regular icosahedron. Since the reflector is formed in this way, the radio wave from all incident angles is reflected.
