Abstract
This document describes the contribution of the Advanced Antenna Technology group (RAATlab) to the design of tri-band antenna terminals for the Canadian Forces. As part of this project, waveguide components in the C, X and Ku bands were studied and designed. The components described in this report are an orthomode transducer (OMT) for the Ku band and a dual-rectangular waveguide to coaxial waveguide transition for the X band. Additionally, a polarizer in square waveguide geometry has been studied and design. Although the tri-band antenna requires coaxial waveguide polarizers, the work performed on the square waveguide polarizer serves as a preliminary investigation into the potentially realizable performance of such polarizers and some of the results obtained could be transposed for the design of the required circular and coaxial polarizers.
