摘　　要：提出1款三谐振结构的宽带反射阵单元,利用HFSS高频仿真软件对该反射阵单元进行反射相位特性分析,结果表明反射阵单元在较宽的频带内能够实现360°以上的相位覆盖,基于该反射阵单元设计了1款7×7的微带反射阵,仿真结果表明,反射阵天线的3dB增益带宽达到了44.7%,最高增益为18.7dBic.In this paper, a broadband reflection array unit with three resonant structures is proposed. HFSS high frequency simulation software is used to analyze the reflection phase characteristics of the reflection array unit. The results show that the reflection array unit can achieve a phase coverage of more than 360 degrees in a wider frequency band. Based on the reflection array unit, a 7×7 microstrip reflection array is designed. The simulation results show that the 3 dB gain bandwidth of the reflection array antenna reaches 44.7%, and the peak gain is 18.7 dBic.
