Abstract
Large beam-waveguide (BWG)-type ground station antennas are generally designed using analysis which ignores the presence of the metallic tube enclosing the BWG mirrors. The common analysis approaches are physical optics and Gaussian mode analyses. The weakness of these analyses is that they do not shed any light on the effect of the metal tube. A BWG analysis which considers the presence of the metal tube is presented. Numerical results of a two-mirror system using the new analysis are compared with experiments which have verified the analysis
