摘要 基于微带天线理论设计了77 GHz微带单辐射贴片天线的基准结构,提出了包含13个微带辐射贴片的基板型十字形阵列天线,对该阵列天线添加超材料覆层结构,利用拓扑优化完成覆层型十字形微带阵列天线设计,并探讨了其高增益机理。仿真结果表明:相比于基板型十字形阵列天线,覆层型十字形微带阵列天线的增益性能提升了35.0%。 Based on the theory of microstrip antenna theory,a reference structure of 77 GHz microstrip single radiation patch antenna was designed,and a substrate cross-shaped array antenna containing 13 microstrip radiation patches was proposed.A metamaterial cladding structure was added to the de‐signed antenna,and topology optimization was used to complete the design of the covered cross-shaped microstrip array antenna,and the high gain mechanism was discussed.The simulation results show that the gain performance of the covered cross-shaped microstrip array antenna is improved by 35.0%com‐pared with the substrate cross-shaped array antenna.
