A dual-layer 3-dB substrate-integrated waveguide power divider/combiner is designed, fabricated, and tested. Very good input and output matching as well as high isolation are exhibited over a measured 50% fractional bandwidth when a 10-dB reference level is considered. A completely shielded design significantly reduces insertion losses when compared to the majority of other state-of-the-art architectures. This device can be integrated with multilayer planar circuits, and it is fully compatible with the standard printed-circuit board technology.
