Multiport power divider-combiner circuits using circular-sector-shaped planar components

A sector-shaped configuration for designing planar power divider-combiner circuits that are compatible with microstrip circuits is discussed. This configuration is analyzed using the two-dimensional planar circuit approach. Expressions for impedance matrix parameters of multiport sectorial planar circuits are given. Theoretical and experimental results reported for 90 degrees and 180 degrees power dividers are in good agreement. >
