摘　　要：本文简要阐述了矩形窄边波导缝隙天线的相关理论,介绍了毫米波窄边波导缝隙行波阵的设计方法。设计过程中利用Ansoft HFSS高频仿真软件来获取缝隙初始导纳参数;并合理选择数据拟合方法和变量形式拟合缝隙电导与缝隙倾角函数。采用该方法设计了中心频率为35GHz的100个单元缝隙的行波直线阵,理论计算时E面副瓣电平按-28dB设计的泰勒分布,仿真得到的最大副瓣为-25dB。This paper describes a rectangular waveguide narrow side slot antenna theory, millimeter-wave waveguide narrow side gap traveling wave array design methods. The design process using Ansoft HFSS high frequency simulation software to obtain the parameters of the the gaps initial admittance; and a reasonable choice of the data fitting methods and variables in the form to fit the gap conductance gap inclination function. The design center frequency of 35GHz 100 unit gap traveling wave linear array, designed by the theoretical calculations E-plane sidelobe level of-28dB Taylor distribution, obtained by simulation the maximum sidelobe is- 25dB.
