Multi-layer 3dB Power Divider Based on Half-mode Corrugated Substrate Integrated Waveguide

In this paper, a double-layer 3dB HMSCIW power divider is designed. The HMCSIW structure is used to design the power divider, the power divider has the advantages of strong coupling of traditional SIW power divider, low cost, simple manufacturing process, etc., and it can also be directly connected to the active circuit. The simulation results show that when the center frequency is 10 GHz, the return loss is better than 18 dB between 8.6GHz and 12.6 GHz, and S12 is equal to S13, which is almost around -4dB, its performance is great. The device is simple to integrate with active circuits.
