Different configurations for the antenna feeder of advanced microwave subsystems are introduced, working in several schemes which combine multiple frequency bands with two linear orthogonal polarisations. The aim of this study is to highlight state-of-art research results on different waveguide components for modern radio frequency (RF)/microwave subsystems, stressing the impact of the selected architecture in the whole system in both the electrical performance and the volume and size of the feeder. Two are the key components of this type of RF/microwave feeder: the ortho-mode transducer for polarisation discrimination and the multiplexers for separating the frequency bands. It will be shown that a careful study of the whole feeder architecture can simplify in some cases the individual components, with the consequent benefit in electric performance and size reduction. The computer-aided design of the presented architectures is outlined, showing examples for different applications and comparing numerical simulations by different methods with experimental results.
