【摘要】：利用双端口双极化微带天线阵元设计了一种中心频率在9.5 GHz的四元Van Atta平面阵,双端口双极化微带天线阵元采用双层介质口径耦合馈电技术。利用高频电磁仿真软件HFSS对阵元及阵列模型进行仿真分析,结果表明:以来波方向-35°,-5°,15°为例,所设计的Van Atta阵双站RCS在-35°,-6°,13°方向达到最大,阵列反向性良好;单站RCS值在-40°~40°来波角度范围内变化小于3 d B,且在前向半空间均大于均匀阵的RCS值,并克服了均匀阵的零陷限制。
[Abstract]:A four-element Van Atta planar array with a center frequency of 9.5GHz is designed by using dual-port dual-polarized microstrip antenna array. The dual-port dual-polarized microstrip antenna array is fed by double-layer dielectric aperture coupling technique. The high frequency electromagnetic simulation software HFSs and array model are used to simulate and analyze. The results show that the bistatic RCS of Van Atta array is the largest in the direction of -35 掳-6 掳~ (13 掳), and the array has a good reversibility, the wave direction is -35 掳-5 掳-5 掳~ (15 掳) as an example. The single station RCS varies less than 3 dB in the range of -40 掳~ 40 掳coming wave angle, and is larger than the RCS value of uniform array in the forward half space, and overcomes the zero trapping limitation of uniform array.
