摘要：
In this paper, two wideband multi-layer substrate integrated waveguide (SIW) power dividers are proposed. Transitions based on microstrip-slotline-SIW coupling for TE40 mode SIW cavities are used to realize the out-of-phase and in-phase difference. The equivalent circuits are used to show the basic design guidelines and impedance matching for the two power dividers. To validate the design, two prototypes over 62.5% fractional bandwidth at 8.5 GHz center frequency are designed, good results can be found between the measurement and simulation results.
