Abstract
In this communication we extend the state-of-the art by providing closed-form equations for
thin-wire elliptical antennas with arbitrary current distributions, valid from low frequencies to
the infrared regime. To this end, we derive an electric-field integral equation (EFIE) for
imperfectly conducting wires and elliptical geometries. Using this formulation, we obtain
unknown arbitrary current distributions through a modal expansion, enabling thus the
calculation of far-fields and other radiation parameters. Results shown not only achieve
remarkable but also to show the superior design possibilities of elliptical geometries in
comparison to the classical circular loops, which may be considered just a particular case of the
methodology here presented. Special attention is paid to mathematical details of electric farfield
equations, thus providing guidelines to produce efficient codes.
