摘　　要：利用基片集成波导结构完成Ka波段罗特曼透镜仿真设计。在设计中基于罗特曼透镜原理与基片集成波导,利用Matlab在HFSS中得到罗特曼透镜轮廓及透镜的结构中旁壁形状,并对基片集成波导缝隙阵列天线进行设计比较,完成对15×32槽多波束阵列天线的设计,设计了一个单层基片集成波导-金属波导垂直转接的结构。最后,将各个部分结合在一起,完成中心频点为35GHz基片集成波导罗特曼透镜多波束阵列天线设计,其带宽为600MHz,增益为27.1dB,扫描角度为90°。A design of Ka band Rotman lens by using substrate integrated waveguide(SIW) is described. Based on the theory of Rotman lens and SIW, the lens contour and side wall shape can be calculated by using Matlab in HFSS. The design of multi-beam array antenna with 15×32 slots can be completed according to the SIW slot array antenna, then vertical transfer structure of SIW to metal waveguide is designed. Finally, these parts are put together, and the design of a multi-beam array antenna which is made up of SIW and Rotman lens is completed with center frequency of 35 GHz, bandwidth of 600 MHz, gain of 27.1 dB and scanning angle of 90°.
