Abstract

A novel approach is applied to the EFIE-MoM analysis of printed antennas, based on the eigenfunctions of suitably extracted singular, frequency-independent parts of the integral operator. These terms, called "static modes", are entire-domain basis functions that extend and generalise the TM and TE modes of a magnetic-wall cavity to arbitrary geometries. General criteria allow to select those modes that efficiently represent the solution, including also "attachment" modes that represent the feed structure discontinuities.
