Decimeter wave planar radiator with reflection attenuation

摘要

The radiator includes a conductive plane (20) positioned above a conductive plane (11) and closed or point-coupled to the plane (11), preferably along its narrow side. This arrangement of planes is arranged over a third conductive plane (60) with circular, elliptical, triangular, square, rectangular, pentagonal or hexagonal boundaries, preferably square boundaries. The conductive plane (20) is galvanically coupled to the inner conductor of a coaxial waveguide.The conductive plane (11) is galvanically coupled to the outer conductor of a coaxial waveguide. The third conductive plane (60) may be a facade, car body or conductive grating
