摘要
Commonly, by virtue of the frequency selective surface (FSS) radome's shape, out-band signals are reflected to other directions to achieve a stealth radome. However, with the development of the anti-stealth of poly-state radar technology, such reflected signals can be still detected. In view of this problem, a novel frequency selective surface loaded with resistance film absorbers is proposed. Such an FSS not only has a stable performance for various incident angles and for different polarizations, but also possesses absorptive property to electromagnetic waves in out-band. By virtue of this advantage, the out-band signals can be absorbed and the risk of anti-stealth detection can be greatly reduced. In addition, because of the function of the absorber, grating lobes of the FSS are also restrained, which reduces the interference of operating band.
