摘　　要：针对低散射微带天线在散射性能和辐射性能之间不易平衡的问题进行了研究,设计了一种基于小型化频率选择表面的辐射散射一体化微带天线;采用弯曲频率选择表面单元支臂,增加频率选择表面臂等效长度的方法,使频率选择表面的尺寸结构小型化;通过优化尖劈状频率选择表面天线罩与微带天线之间的参数,增强了微带天线在工作频带内的辐射性能,缩减了微带天线在宽频带内的雷达散射截面;计算结果表明,频率选择表面与原结构相比尺寸减小了18.5%;实现了与原天线相比辐散一体化天线辐射增益增加了0.26 dB,在1~18 GHz的频率范围内雷达散射截面积均值为-28 dB。Research on the difficult balance between the scattering and radiation performance of low-scattering microstrip antennas was conducted,this paper designed a radiation-scattering integrated microstrip antenna based on miniaturized frequency selective surface(FSS).The bent arm of the FSS unit was used to increase the equivalent length of the FSS arm,and to miniaturize the size and structure of the FSS.The parameters between the wedge-shaped frequency selective surface radome and the microstrip antenna were optimized to enhance the radiation performance of the microstrip antenna within the operating frequency band,and to reduce the radar cross-section of the microstrip antenna in the wide frequency band.Calculation results show that the size of the FSS is reduced by 18.5%compared with the original structure,the radiation gain of the radiation-scattering integrated antenna is increased by 0.26 dB compared with the original antenna,and the average radar cross-section(RCS)is-28.0 dB with a frequency range of 1.0~18.0 GHz.
