A broadband 3-way power divider based on gap waveguide for Ka-band applications

Abstract

The present study aims to design a broadband gap waveguide-based 3-way power divider in Ka-band. Gap waveguide technology is employed to remove serious challenges of fabrication in mmWave frequencies using printed and hollow waveguide technologies. The validation of proposed structure is performed with experimental measurements. There are better isolation and return loss between the output ports than around 20 dB over 27.4–35.1 GHz frequency range. There is less amplitude imbalance between the output ports than ± 0.42 dB. A close agreement exists between measured and simulated results. The results are beneficial for the design, fabrication, integration and expansion of mmWave components.
