Compact W-band multi-layer four-way SIW power combiner/divider
In this paper, a compact W-band multi-layer four-way substrate integrated waveguide (SIW) power combiner/divider is analyzed and demonstrated numerically/experimentally. The proposed power combiner/divider is realized by using a highperformance transition structure between multi-layer SIWs and rectangular waveguide. Both numerical and experimental results indicate that such power combiner/divider shows the high portisolation, low insertion loss, high efficiency, wide band, and small lateral size.
