摘　　要：设计了一种新型双频微带反射阵列。该阵列采用双层结构设计,上层工作于K波段,下层工作于X波段。K波段阵列单元为双方环与圆形金属贴片组合结构,X波段阵列单元为双方环与方形金属贴片组合结构。为了减小两个频段之间的影响,设计频率选择表面代替反射阵面的导体接地板。通过高频电磁仿真软件Ansoft HFSS建模仿真,结果表明:所设计的微带反射阵列有良好的双频工作特性,在频带内有较高的增益,并且很好的抑制了两层反射面之间的互耦效应。A novel dual band microstrip reflectarray antenna is designed.The array is made of two layers,the upper layer is for K band and the lower layer is for X band.The element of the reflectarray for K band is made of two metal square rings and a metal circle patch,the element for X band is made of two metal square rings and a metal square patch.In oder to reduce the relection between two layers,the frequency selective surface is designed to replace the conductor.High frequency electromagnetic simulation software Ansoft HFSS is used to model and simulate the reflectarray.The results demonstrate that the reflectarray designed has a good performance in two bands and the interact between two layers could be minimized.
