摘　　要：层间垂直过渡结构通常被用来实现组件结构的小型化和高密度设计,在毫米波电路布线中起着不可或缺的作用。本文设计了一种可用于Q波段的微带线到带状线的垂直过渡结构,在微带线的末端采用“水滴”匹配结构,以金属通孔连接传输线的形式进行射频信号的垂直传输。运用三维高频电磁仿真软件(HFSS)建立该结构,并与其他类似结构进行性能仿真比对。优化结果表明,这种结构在42~47 GHz频带范围内,反射系数小于-20 dB,带内插入损耗优于0.3 dB,可以满足工程应用的要求。相比同类型的其他垂直过渡结构,本文结构在减小占用面积的同时保持了良好的传输性能。The interlayer vertical transition structure is usually utilized to realize the miniaturization and high-density design of module structure,and plays an indispensable role in millimeter wave circuit wiring.In this paper,a vertical transition structure from microstrip to stripline is studied,which can be used in Q-band.A"water droplet"matching structure is adopted at the end of microstrip line,and the vertical transmission of Radio Frequency(RF)signals is carried out in the form of metal through holes connecting transmission lines.The three-dimensional High-Frequency electromagnetic Simulation Software(HFSS)is employed to establish the structure and compare the performance with that of other similar structures.The optimization results show that the reflection coefficient of this structure is less than-20 dB and the in-band insertion loss is better than 0.3 dB in 42~47 GHz,which can meet the requirements of engineering application.Compared with other vertical transition structures of the same type,it reduces the occupied area and maintains good transmission performance.
