摘　　要：效率高、体积小、质量轻的微波无源器件是5G频段移动通信覆盖的必备设备。文中在研究传统微带型曲折线慢波结构和开路枝节加载基础上,提出基于超宽带慢波微带传输线的设计并进行研究,利用电磁场仿真软件HFSS对该慢波微带传输线进行模拟仿真,仿真结果表明,超宽带慢波结构与普通微带线相比,频带宽,尺寸小,损耗低,成本低,满足5G通信系统的需求。最后通过对加载了所提出的新型慢波微带传输线的小型化U型移相器的实验数据分析表明,该新型慢波微带传输线在基站天线系统中有着广阔的市场应用前景。Efficient, compact, and lightweight microwave passive devices are essential for mobile communication coverage in the 5Gfrequency band. This paper proposes an ultra-wideband slow-wave microstrip transmission line design based on the traditionalmicrostrip zigzag slow-wave structure and the open circuit branched structure. The proposed slow-wave microstrip transmissionline is analyzed and simulated using the electromagnetic field simulation software HFSS. The simulation results indicate that theproposed ultra-wideband slow-wave structure has a wider bandwidth, smaller size, lower loss, and lower cost than the ordinarymicrostrip line, which meets the requirements of the 5G communication system. Finally, the proposed slow-wave microstriptransmission line is analyzed through experimental data of the miniaturized U-phase shifter. The results demonstrate the promisingmarket application prospects of the proposed slow-wave microstrip transmission line in the base station antenna system.
