A measured FSS radome with two absorptive bands separated by one passband

In this paper, a novel FSS radome is developed and measured. This radome has one transparent passband and two absorptive bands. These two absorptive bands are separated by the passband. The radome is manufactured and measured to verify its unique electromagnetic characteristics. In the passband, the gain of the antenna with our radome is only 1~2dB lower than the one of the antenna without any radome. In the absorptive bands, the electric level of the reflected electromagnetic wave from the radome can be 16.5dB lower than the one from a metallic plane with the same size as the radome.
