摘要 为了改善波导缝隙天线的辐射和散射性能,设计了一种方形环结构的完美吸波超材料(Square LoopPerfect Absorbing Metamaterial,SLPAM),其厚度为0.0057λ,最大吸波率达99.9%,并将此材料作为波导缝隙天线的基板,制备了完美吸波基板波导缝隙天线。仿真和实验结果表明:相比普通波导缝隙天线,优化设计的完美吸波基板波导缝隙天线的定向性得到了明显改善,同时其带内雷达散射截面(RCS)得到了有效减缩,最大减缩值达15.7dB。 To improve the radiation and scattering performance of wavegnide slot antenna, a square loop perfect ab- sorbing metamaterial（SLPAM） whose thickness is only 0. 0057λ. but with maximum absorption of 99.9% is designed. A waveguide slot antenna with SLPAM is proposed. Simulated and measured results demonstrate that compared with the conven- tional antenna, the directivity of the novel antenna with perfect absorbing metamaterial is enhanced remarkably, simultane- ously, its in-band radar cross section（RCS） is reduced efficiently, and the largest reduction is up to 15.7dB.
