Abstract

In this letter, a novel numerical technique [1] is applied to the analysis of printed antennas. The technique transforms the flrstkind electric-fleld integral equation (EFIE) into a regularized second-kind equation, via extraction of two singular frequency-independent operators and their numerical inversion. Two options are presented in which the inversion is based on the eigenfunctions of these singular operators, that appear to be the generalization of the TM and TE modes of a magneticwall cavity, coupled by the edge singularities. The example of application shows favorable convergence properties.
