一种微带天线RCS减缩方法与实现

微带贴片天线因其具备的多种优点已广泛应用于通信、雷达等各个领域，微带贴片天线在不影响其辐射性能的前提下，提升其雷达隐身性能即进行 RCS(雷达散射截面)减缩，一直以来都是重要的研究方向。通过分析微带天线 RCS 减缩机理，提出了一种通过对矩形微带天线进行 H 形缝隙加载的方法，提升其雷达隐身性能，实现了天线辐射性影响较小基础上，在 X 波段内天线的 RCS 得到大幅减缩。

RCS Reduction Method and Implementation of Microstrip Antenna

Microstrip patch antenna has been widely used in communication, radar and other fields because of its many advantages. Reduction RCS without affecting its radiation performance has been an important research direction to improve its radar stealth performance. By analyzing the RCS Reduction Mechanism of microstrip antenna, a method of loading H-shaped slot on rectangular microstrip antenna is proposed to improve its radar stealth performance. On the premise of less influence on antenna radiation performance, the RCS of antenna is greatly reduced in X-band.
