Abstract :
This paper presents the radiation characteristics of a slot antenna on a conducting circular cylinder coated with an anisotropic layer. Full wave equations in a cylindrical anisotropic medium are derived from transversal field equations using Fourier series in azimuth φ and Fourier transform in axial coordinate z. The solution is expressed in terms of state transition matrices which are evaluated numerically. Formulation can be easily generalized to multilayered cylindrical structures. Effects of changing different variables such as bias field, thickness of the coating, frequency, etc., are investigated
