Abstract :
Effect on stubs to ferrite microstrip line magnetized to wave propagation was investigated both theory and experiments. Dispersion curve on the line was estimated numerically under parallel plate ferrite transmission line model. Scattering parameters on ferrite microstrip line with stub were also numerically estimated by using HFSS simulator, and proved that wave propagates at negative permeability region of magnetostatic surface wave radiation with left-handed operation. To emphasize interest on effect on stub at strip line, it was developed to coupler and transducers using two lines, and expected their characteristics were observed experimentally.
