On the broadband behaviour of planar elliptical dipole-modal approach

Broadband behavior of planar elliptical dipole structure is analyzed using Illuminatin Modes (IM) approach. The current on patch has been expanded in series of eigenfunctions in form of Mathieu radial and angular functions. The frequency behavior of current distributions and related powers have been discussed to explain the mechanism of broadband operation of the dipole. Different behavior of radiations patterns in wide frequency range have been also discussed and compared to the dipole model simulated in ADS MOMEMNTUM environment.
