Abstract : Both the proper design of slot arrays and the positioning of multiple antenna arrays on a common surface require an accurate estimate of the mutual coupling between individual slot elements. To date, the analysis of mutual admittance has been undertaken for slot elements in simple shapes such as circular cylinders, cones, and spherical surfaces. Limited attempts have also been made to treat more general surface shapes using asymptotic methods. In an effort to extend this type of analysis to arbitrary geometries, the present investigation considers a numerical solution for the mutual coupling between individual, finite-sized slots in an infinite, conducting cylinder of arbitrary cross section. Both axial and circumferential slots are considered.
