Microstrip discontinuity modeling

The authors describe a technique by which fast and accurate expressions can be obtained for the lumped elements of equivalent circuits for microstrip bends. It is based on fitting measured data to empirical expressions. It can be applied to any microstrip discontinuity, and if enough data are available for the curve-fitting techniques to properly characterize the discontinuity, all the important parameters can be considered. In describing the technique, the authors focus on the bend discontinuity and report the inductance, and capacitance of the equivalent circuit as calculated by an expression developed with this technique
