Abstract: A radome having multi-size metal patterns and a radar device using the radome are provided. The radome includes alternately-arranged dielectric substrates and metal layers. Each metal layer includes metal frames and metal patterns wherein the metal patterns are electrically insulated from each other. A gap width corresponding to one metal pattern of one metal layer is a width of a gap defined between the metal pattern and a nearest metal frame to the metal pattern. The gap widths corresponding to the metal patterns are increasing, decreasing and further increasing in sequence along a radial direction extending from a center to an outer edge of the metal layer. The outmost layers at both sides of the radome are metal layers. The metal layers have substantially identical layout.
