Abstract: A radome for protecting a radar device is disposed in the transmission path of signals to/from the radar device. The radome includes a shell; a first circuit board disposed at a side of the shell facing a radar device to be protected, and configured with a first inner circuit ring and a first outer circuit ring facing toward the shell; a second circuit board disposed between the first circuit board and the shell, and configured with a second inner circuit ring and a second outer circuit ring facing toward the shell; a first insulation layer disposed between the first circuit board and the second circuit board; and a second insulation layer disposed between the second circuit board and the shell. The first and second inner circuit rings are enclosed with and insulated from the first and second outer rings, respectively, and each of the circuit rings forms a closed loop.

Abstract: A radome is provided for covering an antenna. The radome is disposed in a transmission path of a radiation from the antenna and modifies a radiation pattern of the antenna when the radiation from the antenna penetrates therethrough. The radome has a first surface and a second surface opposite to the first surface and facing the antenna, and includes a plurality of through holes penetrating through the first and second surfaces and having first and second openings on the first and second surfaces, respectively. The first openings of the through holes are allocated in at least a central area of the first surface, an inner annular area of the first surface surrounding the central area, and/or an outer annular area of the first surface surrounding the inner annular area in a manner that an area-averaged permittivity is increasing radially outwards from the central area toward the outer annular area.
