Abstract :
This paper deals with the problems that arise when physically large systems, such as a digital switching exchange for high speed broadband applications, must be tested in order to comply with the EN 55022 standard for radiated emission. Simple closed formulas to predict radiated emissions from elementary sources, such as tracks in PCBs, cables, and small apertures, are outlined with their limits of application and verified by measurements. An analysis of the radiation patterns of simple structures and complex systems is also given
