Abstract :
A full-wave spectral-domain analysis of compensation for a variety of microstrip discontinuities, including open-ends, bounds and T-junctions, is presented. To properly model the discontinuities with miters as well as 90° corners, vector-valued triangular subdomain functions are used as both expansion and testing functions in the moment method procedure. Special consideration is given to the numerical treatment of the reaction integral between two triangular subdomains such that rather complicated geometrical configurations can be handled very efficiently. Comparison of some numerical results with available experimental data shows excellent agreement. The losses due to radiation and surface waves for some discontinuities are also included
