Abstract:

A circularly polarized wave is the resultant of two plane polarized waves of the same frequency and magnitude traveling along a common axis of propagation, polarized at right angles to one another and differing in time phase by 90 degrees. UHF techniques producing circular polarization can employ turnstile, dipole-loop, or helix antennas. At microwave frequencies, optical techniques can be used to transform in waveguide or free space an already launched linearly polarized wave into a circularly polarized wave. A circularly polarized antenna will not receive its own echo unless the transmitted wave undergoes two reflections. Author
