They are metallic tubes made often of high quality material (copper, brass – partially silvered or gold plated). A waveguide may have rectangular, circular or elliptical cross section. The rectangular waveguide is most commonly used for relatively short connections.  Waveguide has a number of advantages over coax, microstrip and stripline. It is completely shielded , it can transmit extremely high peak powers and it has very low loss at microwave frequencies. The main advantage is that waveguides support propagation with […]
