Abstract :
In this paper, the boundary condition characteristic equation of the anisotropic-dielectric-loaded corrugated guide is developed. Dispersion curves of hybrid modes generated by the characteristic equation are presented and discussed. This paper also presents a technique to reduce the relative permittivity and create uniaxial anisotropy from isotropic homogeneous dielectric. Radiation Patterns are generated and a parametric analysis of cross-polar level versus frequency is conducted.
