| 摘 要： | 波导缝隙阵列天线具有结构紧凑、性能稳定等优点被广泛应用于雷达及卫星系统中,然而该天线会产生较强的雷达散射截面。文中采用在波导缝隙阵列天线上放置开槽的EBG结构,对其RCS减缩进行了研究。结果表明,在不影响天线辐射特性的情况下,加载该EBG结构可以有效地减缩波导缝隙天线的RCS。

| Abstract: | Due to the well-known characteristics such as compact structure and stable performance,waveguide slot antennas are widely used in various fields,though this kind of antennas can generate very strong Radar Cross Section(RCS).This paper studies the reduction of RCS about waveguide slot antennas by using two different EBG structures.The results show that the EBG structure has a good performance for reduction of RCS. |

| Keywords: | waveguide slot antenna radar cross section electromagnetic band gap |
