摘要

在低可观测技术中，低雷达截面(RCS)但高增益的天线是首选。本文利用相位抵消的概念，设计了一种低RCS微带贴片阵列。贴片元件依次或随机旋转，保持进给固定。这种贴片元素的几何排列有效地减少了散射。分析了随机旋转微带贴片阵列的增益和RCS，并与无单元旋转和顺序旋转贴片阵列进行了比较。结果表明，在不影响其辐射性能的情况下，显著降低了RCS。

Low RCS microstrip patch array: EM design and performance analysis

In low observable technology, antennas with low radar cross section (RCS) but with high gain are preferred. In this paper, a low RCS microstrip patch array is designed using the concept of phase cancellation. The patch elements are rotated sequentially or randomly keeping the feed fixed. This geometric arrangement of patch elements reduces the scattering effectively. The gain and the RCS of randomly rotated (RR) microstrip patch array is analyzed in comparison with a uniform array with no element rotation (NR) and sequentially rotated (SR) patch elements. It is shown that the RCS of the RR array is reduced significantly without any adverse effect on its radiation performance.
