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.
