A radome and a radar device using the radome are provided. The radome is made of a dielectric material. A thickness of the dielectric material is first increased and then decreased along a radial direction extending from a center to an outer edge of the radome. The radar device includes the radome and an antenna transmitting or receiving electromagnetic waves passing through the radome.

Radome and radar device using the same

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.
