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.
