Waveguide Components

Waveguide components such as waveguides as transmission lines, mode transducers, terminations, discontinuities, attenuators, phase shifters, multiport junctions, directional couplers, filters, diplexers, and multiplexers are extensively employed in industry to produce waveguide subsystems for a wide variety of microwave and millimetre wave applications. Waveguide components, in general, are constructed from elements of the transmission structures and it is essential to understand the electromagnetics of the situation. This chapter attempts to illustrate the basic considerations by referring to a few of the more important rectangular waveguide components employed in microwave and millimetre wave systems. It is hoped that the references included at the end of this chapter will direct the interest reader to sources of more detailed information on particular subjects
