A method for controlling polarization structure of a field generated by a spiral cone antenna

L. M. Lobkova, A. V. Lukyanchikov

Abstract


A method of controlling polarization structure of radiation, allowing to decrease the losses due to the mismatch in antennas polarization by 3 dB, is suggested on the example of a four-turn spiral antenna. The experimental research results of a switching device allowing to realize the necessary amplitude-phase excitation of each spiral turn within the radiator are presented.
