Design of a substrate integrated waveguide based 1-to-6 non-uniform power divider

In this paper, we have presented an original design of a SIW based planar integrated l-to-6 non-uniform power divider for low sidelobe array antenna applications. This design is more compact and more efficient than many SIW based or microstrip based power dividers. With this design concept, one can design non-uniform power dividers with good amplitude and phase balance. This design can also be easily fabricated and conveniently integrated with other subsystem for a low cost, high performance and integrated system solution.
