Optimized power dividers based on E-plane T-junctions

A power divider is an essential component in the design of antenna feed net works for satellite applications. Asymmetrical E-plane T-junctions exhibit good electrical performances and a simplified mechanical process of constru ction. This paper study improved structures on this baseline. These are ana lyzed and optimized. Two different analysis methods have been used in order to check their results. Also, the results have been verified with commerci al software. Both methods are based on the GSM (general scattering matrix) and modal analysis technique. The optimization process, based on quasi-Newt on approximations, allows obtaining for instance, a power divider with five ports (four T-junctions cascaded) with good electrical performances. A tol erance analysis has been carried out in order to study the feasibility of p ower dividers. (C) 2001 John Wiley & Sons, Inc.
