Analysis of a printed dipole antenna on a general anisotropic substrate with the method of moment employing eigenvector dyadic green´s functions

The method of moments solution for a printed dipole antenna on a grounded general anisotropic substrate is formulated with the eigenvector dyadic Green´s functions. The general feasibility of this method is validated by checking the numerical results of a printed dipole on isotropic, biaxial and ferrite substrates with the previous work in which different dyadic Green´s functions are used. Furthermore, this method is utilized to study the effect of the biasing magnetic field to the resonant length and radiation patterns of a printed dipole on a gyroelectric substrate.
