1×4 SIW mmWave Power Divider Transition Structure

The article proposes a 1×4 SIW mmWave power divider, using ceramic as the substrate. There are four ports in total, one input, and four outputs. The simulation results show that the phases of the four output ports are the same, which means that the output signals of the ports will not interfere with each other. At the same time, the insertion loss of the four output ports ranges from −7.3dB to −7.6dB, achieving efficient signal transmission performance.
