Abstract :
A generalized method for calculating both radiation and surface-wave losses is developed for microstrip discontinuities. The losses are determined by a rigorous Poynting vector analysis where the current distribution over the microstrip discontinuities is a result of a full-wave moment-method solution. It is found that above a certain frequency, the surface-wave loss becomes more important than the radiation loss. A self-consistency check of the result based on power conservation is also presented.<>
