Abstract
In this paper, the boundary condition characteristic equation of the anisotropic-dielectric-loaded corrugated guide is developed. This complex guide has potential application in wideband low cross-polar radiators and microwave transitions. 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.
