Optimum shape design of matching stubs based on full-wave analysis
H.-B. Lee, D. Koh, T. Itoh, Frank J. Villegas, H. Alfred Hung · 2002
The shapes of matching stubs are designed with an optimizer based on full-wave analysis. By selecting the shape of matching stub as the design parameter, compact circuits for matching could be obtained. FEM is used as a full-wave analyzer, and adjoint variable method is adopted for sensitivity analysis.
