Substrate integrated waveguide (SIW) is a new type of waveguide structure, which has a lot of advantages on high Q, low loss, low radiation and so on. Because of its unique structure, it is very easy to be integrated in the planar circuits. This paper mainly introduces an efficient type of transition between SIW and rectangular waveguide, and a two-way SIW power divider at w-band. Using full-wave...
An out-of-phase broad-band substrate-integrated waveguide power divider is proposed. The divider uses a folded substrate-integrated waveguide to split an input signal into a pair of half-mode substrate-integrated waveguides. Due to the field distribution in the folded substrate-integrated waveguide, this power split is out-of-phase. Broadband performance is achieved due to the similar field distributions...
In this study an X-band SIRW power divider/combiner structure was designed using a cheap dual layer PCB. The designed structure was then simulated and optimized design was fabricated. The critical analysis of the simulated and the measured results was performed. The final results were very close to the expected results with -3.17 dB output and -32 dB return loss.
