摘要: 本文基于人工磁导体结构与缝隙天线理论设计了一款低RCS天线。首先基于人工磁道体理论设计出人工磁导体单元，两个单元之间满足(180˚ ± 30˚)相位差，将两种天线单元按棋盘结构交叉排列构建天线阵列，天线阵列在平面波的激励下实现了12.7~29.3 GHz内10 dB以上的单站RCS缩减，天线阵列的双站RCS也得到了缩减，入射波在不同方向上被分成6个波瓣；其次，设计一款缝隙天线来代替天线阵列的中心单元组成新的天线阵列，加载人工磁导体后缝隙天线的性能得到了一定的优化，同时新天线阵列可实现12.2~33.4 GHz范围内6 dB以上的单站RCS缩减和一定角度范围的双站RCS缩减。
Abstract: In this paper, a low-RCS antenna is designed based on the artificial magnetic conductor (AMC) structure and slot antenna theory. First, an AMC unit cell is designed according to the artificial magnetic conductor theory, with a phase difference of (180˚ ± 30˚) between the two unit cells. The two types of AMC unit cells are arranged alternately in a chessboard configuration to construct an antenna array. Under plane-wave excitation, the antenna array achieves monostatic RCS reduction of more than 10 dB within 12.7~29.3 GHz, and its bistatic RCS is also reduced, with the incident wave split into six lobes in different directions. Next, a slot antenna is designed to replace the central element of the antenna array, forming a new array. After loading the AMC structure, the performance of the slot antenna is improved to a certain extent. Meanwhile, the new antenna array realizes monostatic RCS reduction of more than 6 dB in the range of 12.2~33.4 GHz and bistatic RCS reduction within a certain angular range.
