RADIATION CHARACTERISTIC OF SLOTS ON CONDUCTING CIRCULAR-CYLINDER COVERED BY ECCENTRIC DIELECTRIC CYLINDER

The radiation characteristics of axial slots on a circular conducting cylinder covered by an eccentric dielectric cylinder are investigated. A dual infinite-series solution based on the boundary-value method is obtained with the aid of the addition theorem of Bessel functions. Th e dual infinite series involved in the solution is then properly trunc ated to generate numerical results. Comparison with published data for concentric cylinders shows excellent agreement. Several interesting r adiation characteristics corresponding to new geometries of the coated slot cylindrical antenna are presented.
