Research on RCS Reduction Technology of Microstrip Antenna

摘要: 设计一款常规微带天线，保证其工作带宽和增益良好。然后，结合RCS减缩技术中的短路探针加载、贴片小型化、接地板开槽等技术对微带天线进行依次处理，对比参考天线与技术处理后天线的RCS，即保证了天线辐射的工作性能，又能实现RCS减缩的效果，验证短路探针加载、小型化、开槽技术的可行性、有效性。在此基础上，加载AMC棋盘式结构，进一步提高RCS的减缩量。

Abstract: A conventional microstrip antenna is designed to ensure good operating bandwidth and gain. Then, combined with the short-circuit probe loading, chip miniaturization, grounding plate slotting and other techniques in the RCS reduction technology, the microstrip antennas are sequentially processed, and the RCS of the reference antenna and the technically processed antenna are compared. Then, the antenna radiation work is ensured, and can achieve the effect of RCS reduction, verify the feasibility and effectiveness of short-circuit probe loading, miniaturization, and slotting technology. On this basis, the AMC checkerboard structure is loaded to further increase the amount of RCS reduction.
