摘　　要：对矩形微带串馈梳状天线阵的设计理论和方法进行了研究,从等效电路中分析得到阵元参数的提取办法。采用加四分之一波长阻抗变换段的方法,降低串馈阵的副瓣电平。在理论的基础上,设计了1×8的矩形微带串馈阵,使用HFSS对其阵列进行仿真,结果达到要求的指标。The design theory and method of rectangular microstrip comb antenna arrays are studied,and the equivalent cirsuit is analyzed to obtain an extracting method for the array element parameters. The side lobe level（ SLL） of series-fed microstrip arrays is reduced by using quarter-wavelength transformer.The 1 × 8 series-fed rectangular microstrip antenna array is designed on basis of the theory,and the array is simulated by HFSS. The results show that the required specification is achieved.
