摘要
提出了一种改进的小型化低雷达散射截面(Radar Cross-Section,RCS)圆极化微带天线.基于天线的辐射接收理论,研究天线散射的基本理论,提出了该圆极化天线散射的分析与控制方法.对典型的圆极化微带天线,通过在天线地板上添加圆形和矩形结构,令参考天线在保持电性能指标不变的前提下,实现了天线的小型化和低RCS特性.实验结果表明:天线的RCS被明显降低,具有大于50%的小型化效果.
Improved miniaturized and low radar cross section （RCS） microstrip an- tenna is proposed for circularly polarized applications. The antenna scattering theo- ry was given based on the theory of antenna radiation and scattering. The method of analyzing and controlling the scattering of circularly polarized microstrip antenna was also given. By the introduction of several circular and rectangular slots on the ground plane of the reference antenna, its RCS＇and size were reduced without effects on the circular polarization performances. The radiation and scattering char- acteristics were simulated and compared. The results show that the size of the pro- posed antenna is 50G smaller than the reference antenna, and the RCS of the refer- ence antenna is also reduced.
