Design of broadband power divider based on Substrate-Integrated Waveguide technology

In this paper, design principles for implementation of broadband T-type and Y-type power divider based on Substrate-Integrated Waveguide (SIW) technology has been presented. Different design curves have been developed based on simulation results and are used to implement 1×2 power dividers of Y-type and T-type. Finally, by cascading T-type and Y-type stages a 1×4 Power divider of equal division is designed and simulated. The proposed design shows a broad bandwidth (-20 dB) of 18.3% and insertion-loss Bandwidth (1%) of 17.86%.
