Abstract :
This paper presents a full-wave analysis method for printed apertures in anisotropic stripline structures. Both electric and magnetic anisotropy of the most general form are assumed. Working in the Fourier domain, closed form expressions for the transformed electromagnetic fields are derived. Special attention is dedicated to the particular case of dielectric uniaxial anisotropy. In this case, spectral Green´s functions in compact and closed form are obtained. Guided modes in the anisotropic layers sandwiched by the ground planes are also analyzed
