Abstract :
The analysis and modeling of microstrip open-end and gap discontinuities in a substrate-superstrate structure using the numerical solution of integral equations is presented. Good accuracy is achieved by adopting semi-infinite subdomain mode expansion functions, with a transverse coordinate dependence obtained from a two-dimensional finite-line analysis. A parametric study of the material layer effects of radiation and surface wave losses and the fringing fields at the discontinuities is performed
