Abstract :
A mixed (scalar and vector) potential surface integral equation formulation, originally developed for microstrip antennas by Mosig and Gardiol (1982), is used to compute the radiated emission from printed circuit traces that involve right-angular bends and gap discontinuities. Computed results for a gap-excited trace configuration loaded by a short circuit or an open circuit indicate good agreement between a quasistatic approximation of the trace current and a rigorous mixed-potential computation
