Design and Analysis of a $1 \times 2$ SIW 28GHz Ceramic Power Divider for High-Frequency Applications

This article proposes a $1 \times 2$ SIW 28 GHz power divider. The substrate uses ceramics and has a lower loss tangent, which is suitable for high-frequency applications. There are three ports in this structure, one input and two outputs. The simulation confirms that the phases of the two output ports are the same, and the addition of End launch simulation increases the reliability of the actual measurement. Finally, the insertion loss of the two analog output ports Port2 and Port3 are both -4 dB, indicating good transmission.
