摘　　要：针对单层双平板微带反射阵天线带宽窄的问题,采用双层贴片反射板形式设计了一个K波段的双层双平板微带反射阵列天线,并进行了仿真计算,在相对带宽为10%的工作频带内,增益起伏<1.5 d B。通过与单层双平板微带反射阵列天线的结果进行对比分析,证明了该设计方法的正确性和可行性,可用于设计带宽要求较高的微带反射阵列天线。According to the narrow band width of single - layer dual planar microstrip reflectarray antenna, a K band two - layer dual planar mierostrip reflectarray antenna with the use of double layer microstrip patch reflector plate has been designed. The antenna has been simulated and the results indicate a gain fluctuation of less than 1.5 dB within 10% relative bandwidth of working frequency band. Comparison with the results of single layer dual planar microstrip reflectarray antenna shows that the design method is correct and feasible, and can be used to design the microstrip antenna with high bandwidth requirement.
