Abstract :
The attention to coaxial waveguide polarizers is caused due to developing multifrequency antenna systems, e.g. for radio telescopes, operating over two or more sufficiently spaced frequency bands. If the inner conductor is hollow and acts as a conventional circular waveguide, it can be used for transmitting a higher-frequency signal while the coaxial region provides the lower-frequency signal propagation. The further addition of outer cylindrical conductors allows increasing a corresponding number of frequency bands.
