Theory and experiment on rectangular coaxial line discontinuities and junctions

Step discontinuities and junctions in rectangular coaxial lines are analyzed both theoretically and experimentally. The theoretical approach is based on a modified field matching technique extended to 3-D problems for the analysis of multiaxial discontinuities. In spite of the complexity of the boundary value problems involved, the computer analysis is performed on a PC. Experiments in the 2-6-GHz band show excellent agreement with the theoretical predictions.<>
