Análise de junções cruzadas e junções-T em microfita a partir da aplicação da CCPT.

Abstract

This dissertation presents the application of the Power Conservation Technique Complex, the Generalized Spreading Matrix and the Waveguide Model Equivalent in the characterization of parameters intrinsic to structures with discontinuities bi-dimensional (effective width, dielectric constant and impedance characteristics) and scattering parameters (transmission and reflection). The techniques and modeling are used in the characterization of cross-junction discontinuities and symmetric T-junction in microfita. These two types of structures are modeled using the Waveguide Model Equivalent. And a study of the propagation of the signal in the structures, in terms of transmitted and reflected power, using the Complex Power Conservation Technique. Then, the matrix S with its scattering coefficients is obtained by applying the Matrix Technique Generalized Spreading to structures. From the cross-junction analysis and the symmetric T-junctions using the techniques and modeling cited above, is developed and implemented software that characterizes these structures in terms of intrinsic and scatter parameters. This software is another tool computational method useful in the characterization of the bi-dimensional discontinuities of cross-join and symmetric T-junction. The results obtained are in line with the with the specialized literature, in the frequency range considered (up to 20 GHz). Also shown are flowcharts that facilitate the monitoring and analysis of the program implemented.
