摘要/Abstract

摘要：

给出了一种极化稳定、宽入射角、无表面损耗层的超薄超材料吸波体，并将其用于波导缝隙天线，降低天线带内雷达散射截面．理论分析与仿真、实测结果表明: 该吸波体最大吸波率达99％，厚度仅为0.0057λ，通过优化其在天线辐射缝隙周围的排列分布，使天线带内雷达散射截面在-21°至+21°角域减缩超过3dB，法线方向雷达散射截面减缩在13dB以上，同时天线增益提高了0.99dB．

关键词: 超薄超材料吸波体, 波导缝隙天线, 雷达散射截面

Abstract:

An ultra-thin metamaterial absorber with polarization stability, a wide incident angle and no surface ullage layer is proposed and applied to the waveguide slot antenna to reduce its in-band Radar Cross Section(RCS). Theoretical analysis, and simulation and experimental results demonstrate that the absorber can exhibit an absorption of 99％ with thickness of only 0.0057λ, that when applied to the waveguide slot antenna in an optimized distribution, it can reduce the in-band RCS of the antenna for more than 3dB from -21° to +21°, that the largest reduction value exceeds 13dB in the normal direction, and that it can increase the gain by 0.99dB.

Key words: ultra-thin metamaterial absorber, waveguide slot antenna, radar cross section
