A rigorous approach for studying primary sources Applications for satellite antennas
Abstract
A rigorous mathematical treatment was developed for radiation patterns with a symmetry of revolution. An integral equation is obtained for the electric field, with the sources decomposed into azimuthal modes. A method of moment is applied to solving the equations for the current densities and the reflection factor is quantified. The method is employed to characterize the radiation fields of a waveguide with a circular aperture, that of a satellite bifocal reflector for global coverage and a lobe antenna consisting of a reflector fed by a matrix of circular guides for continental coverage.
