摘要
设计了一款频率选择表面和微带贴片天线阵,分析了阵列天线的雷达横截面积(RCS)随入射电场波角度以及频率的变化,并对比加了频率选择表面前后天线RCS的变化,讨论了频率选择表面对阵列天线RCS的影响。从计算结果可以看出,频率选择表面作为天线罩以降低电子设备RCS值是可行的。
This paper designs a microstrip patch antenna array with frequency slective surface,analyzes the change of radar cross section（RCS）of array antenna along with the change of incidence electric field wave angle and frequency,and compares the change of antenna RCS before and after adding frequency selective surface（FSS）,discusses the influence of FSS on the RCS of array antenna.Calculation results show that the feasibility to reduce the RCS of electronic equipment by appylying FSS to a radome.
