基于宽带吸波体的低雷达散射截面平面印刷磁电偶极子天线设计

摘要
该文设计了一种工作于X波段的平面印刷磁电偶极子天线,并设计了一种加载集总电阻的宽入射角、极化不敏感、宽频带吸波体(WBMA)。当平面波垂直入射时,吸波体在7.2~12.6 GHz范围内的吸波率大于90%,入射角增加至45?时仍能在X波段保持90%以上的吸波率。通过将WBMA加载在天线四周,实现了天线雷达散射截面(RCS)的大幅缩减。实测和仿真结果表明:不同极化波垂直入射时,天线单站RCS减缩3 d B带宽为6.6~14.4GHz,最大减缩量达23.8 d B。中心频点10 GHz处,TE极化波照射时,双站RCS能实现?90?角域内的减缩,TM极化波照射时,在?35?角域内实现了减缩,同时天线辐射性能几乎保持不变。
A broadband planar printed Magneto-Electric(ME) dipole antenna and a Wide-Band Metamaterial Absorber(WBMA) with polarization-insensitive and wide-angle absorption are designed for X band application. The absorber exhibits absorptivity above 90% from 7.2 GHz to 12.6 GHz under normal incidence. When the incident angle increases to 45?, the absorptivity is still above 90% at X band. By applying the absorber around the antenna, the RCS of antenna is reduced significantly. Simulated and experimental results show a monostatic RCS reduction above 3 d B from 7.2 GHz to 12.6 GHz, and the peak reduction is up to 23.8 d B under different polarized waves. At the center working frequency of 10 GHz, the bistatic RCS decreases significantly from-90? to +90? under TE polarized wave and from-35? to +35? under TM polarized wave while the radiation performance remains unchanged basically, which proves that the absorber has great absorptivity.
