5-Way branch line power divider on planar structure

In this paper, first, an analysis method with scattering matrix is proposed to analyze a power divider. Then, a new structure of power divider, in which isolated ports are grounded, has been developed to low the complexity of fabrication and cost. Comparisons between the present theoretical results and simulation results validate the present analysis method. Finally, a 5-way power divider has been designed and fabricated, simulation and measurement reveal its high isolations and good performance.
