摘　　要：本文提出了1种基于三明治结构双圆组合贴片的宽频带高功率反射阵列天线。通过将贴片埋藏于介质内部,实现了天线功率容量的提升。采用旋转贴片转角的方式实现360度的相位调控,从而实现天线宽频带性能。基于单元天线设计了9x9反射阵列天线,仿真结果表明,在工作频率9.3GHz下,该反射阵列天线的增益为22.8dB,口径效率为53.9%,主波束方向的轴比为0.33dB,1-dB增益带宽约为17.8%,在1个气压SF。气体环境中的功率容量为109.3MW。A wideband high-power reflectarray antenna based on the sandwich combined double-circle patch is proposed in this paper.By embedding the patch into the substrate,the power capacity of the antenna is improved.The patch is rotated to achieve 360°phase adjustment,thereby the wideband performance of the antenna is achieved.A 9x9 reflectarray antenna is designed and simulated.The simulated results show that at the operating frequency of 9.3 GHz,the gain of antenna is 22.8 dB,with the aperture efficiency of 53.9%,and the axial ratio at the main beam direction is 0.33 dB,the 1-dB gain bandwidth is about 17.8%,and the power capacity is 109.3 MW in one atm of SF6 gas condition.
