Abstract
In this paper, a new eigenmode algorithm, based on the method of lines and the generalized transmission line (GTL) equations is applied on full-wave analysis of (3-D) MMIC components. The analytical calculation in the direction of propagation enables the analysis of structures of very short or long interconnections between single discontinuities. The analysis is developed by non-distant discretization to reduce the discretization window. This technique is applied to compute the scattering parameters of a six coupled microstrip lines band pass filter. A neural network approach is used for optimizing the scattering parameters of the band pass filter to improve its performance. The optimized filter is fabricated and its performance is measured. Good agreement is found between numerical and exponential results.
