On the Design of Optimized Microstrip Radial Line Power Dividers

The planar realization of beam forming networks for active antenna systems in satellite communication requires small and high performance power splitters. The microstrip radial line power divider seems to be a suitable structure for this purpose, because, under certain hypothesis, insures an equiphase and equiamplitude power splitting. A design procedure which assures the realization of optimized n- way radial line dividers is proposed and the corresponding design charts are given. Moreover good agreement between experimental and theoretical data from different sources is demonstrated.
