Method of moments applications. Volume 6. Matrix methods for static microstrip
Abstract
Matrix methods are applied to static microstrip problems and used to deduce the approximate propagation characteristics of the dominant, quasi-TEM mode. Three basically different techniques are employed, in conjunction with the matrix methods. The first uses a free space Green's function, the second uses multiple imaging to obtain a Green's function for single substrate microstrip, and the third uses Fourier integral methods to obtain the Green's function for multilayered and/or covered microstrip. Several classes of problems are treated. The capacitance matrix, propagation constant, and characteristic impedance are obtained for two-dimensional (transmission line) problems. In addition, a general method for treating capacitive discontinuities in microstrip is developed and applied to typical three-dimensional discontinuity problems such as an open circuit, a gap in microstrip, and a sudden change in width of microstrip. Finally, multilayered and covered microstrip propagation is analyzed by a Fourier integral method.
