Evaluation of Impedance Matrix Elements for Microstrip T-Junction Discontinuity

The paper deals with prior introduction to the calculation of the impedance matrix elements for the investigated microstrip structure. The analytical and numerical-analytical approaches for investigation of the full-wave radiation in the microstrip discontinuities are presented. The components of electrical field are determined from the appropriate Pocklington's equation. The application of the Galerkin's procedure yields in the matrix equation. The elements of received matrix are calculated by the combination of the analytical and numerical methods.
