一种新型开槽结构减缩微带天线RCS
录入：edatop.com 点击：
内容简介：现有开槽技术减缩微带天线RCS是以牺牲辐射性能为代价,文中提出了一种圆形槽与矩形槽相结合的开槽方式,这种方式可以实现RCS的有效减缩。理论分析和仿真、实测结果表明,该方法设计的微带天线在辐射性能没有变化的同时,在4～8GHz频率范围内单站RCS有了较大幅度的减缩,最大减缩量达到了22dBsm。
Abstract：The technology of cutting slots in the microstrip patch is used for the radar cross section（RCS） reduction at the cost of radiation performance.A novel cutting slots scheme which combines circular slot with rectangular slot is presented in this paper,it can reduce the RCS of the antenna effectively.Simulation and measured results and analysis demonstrate that this slots antenna can not only guarantee the antenna radiation performance,but also reduce the RCS of the antenna significantly at frequency range from 4 GHz to 8GHz,the largest reduction is up to 22dBsm.
