Abstract

This paper is intended to describe an efficient numerical method to predict the radiated emissions from PCBs. We start with the computation of the inductance, capacitance, resistance, and conductance distributed matrices. A Pspice lumped circuit model is then used to calculate electric currents on different traces. Antenna theory is used to calculate the radiated fields from different traces. From a numerical modeling point of view, the shape, geometrical configuration, material, and size of PCBs as well as the frequency range of operation are of particular relevance.
