✦ Synopsis
Based on a waveguide analysis model for discontinuity in microstrip line circuits, the model-matching method and the generalized scattering matrix method were used. The effective dielectric constant and effective width of linear and raised cosine tapers were considered by approximate step analysis, and the return loss was calculated. Our results indicate that the characteristic is much better for a linear taper when the length of taper exceeds a certain value. Shape evaluation was performed with the characteristic defined by a property chart. The return loss of a circuit with the same taper in the input and output was analyzed.
