ABSTRACT: The radiation characteristics of waveguide antennas located on the surface of a circular cylinder are investigated theoretically and numerically. A reactive impedance structure is used to provide reduced coupling between two antennas on the surface of a cylinder. Using the moment method, a solution to the problem of the radiation of a single and two parallel-plate waveguides located on the surface of a reactive impedance cylinder is derived. The influence of the reactive impedance structure on the coefficient of standing waves, the radiation patterns, and the decoupling between antennas is studied.
