Abstract

A procedure for numeric evaluation of radiated emissions from polygonal wire antennas is presented in an EMC context. The propagation problem is solved with an application of the well-known method of moments, using piecewise sinusoidal expansion functions. The availability of closed-form expressions for the radiated fields from linear dipoles with a piecewise sinusoidal current distribution and the superposition principle allow an accurate evaluation of the radiated field from a polygonal wire antenna. The presence of angles introduces a drawback that has been solved imposing a condition of continuity for the current, that is, by applying the Kirchhoff´s current law. Some numerical results for a practical application are presented and discussed
