摘　　要：针对多层毫米波的射频传输问题,设计了一种宽带射频垂直过渡结构。通过调节微带线枝节与绝缘子之间的匹配关系,使射频信号在多层介质基板中实现低损耗、宽频带的传输。利用三维电磁仿真软件对该过渡结构进行了建模仿真,实物加工和测试结果表明,在DC至40 GHz的频带范围内回波损耗低于-8 dB,插入损耗大于-2.2 dB。A wideband RF vertical transition structure is designed for the RF transmission problem of multilayer millimeter waves.By adjusting the matching relationship between the microstrip wire branches and insulators,the RF signal can be transmitted in multilayer dielectric substrate with low loss and wideband.The 3D electromagnetic simulation software is used to model and simulate the transition structure,and the physical processing and testing results show that the return loss is less than-8 dB and the insertion loss is greater than-2.2 dB in the frequency band from DC to 40 GHz.
