The ever‐growing use of anisotropic ferrite devices in modern wireless communication systems highlighted the need for robust design tools to reliably characterize the dispersion behavior of such devices in radio frequency (RF)/microwave bands, especially for multilayered configurations. Indeed, as ferrites present a biaxial anisotropy, spectral analysis of multilayered configurations with such substrates is not generalized, however, restricted to some particular cases of tensors. Therefore, this article deals with the characterization of anisotropy effects on the dispersion parameters of multilayered wireless circuits with ferrite substrates, particular case of gyrotropic medias. In the proposed approach, a rigorous analysis was carried out by taking into account, for the first time, the electrical aspect of anisotropy. The computed results are in good agreement with those available in the literature. © 2011 Wiley Periodicals, Inc.
