DESIGN CURVES FOR A CIRCULAR POLARIZER

reportActive / Technical Report | Accession Number: AD0417184 | Open PDF

Abstract:

A common method of producing a circularly-polar ized wave in a constant cross section waveguide consists of exciting two waves which are linearly polarized and mutually orthogonal. Adjusting the relative phase velocity of the two waves enables one to produce a single wave which is circularly polarized. Occasionally it is desired to produce right-hand circular polarization at one frequency and left-hand circular polarization at another. The design parameters are usually the ratio of cut-off wavelengths of the two waves, the length of the polarizing section and the frequencies of operation. The theory of operation and a set of design curves showing the relationship between the parameters are presented.
