Reduction of the Parasitical Signal of Circular Polarization on an Antenna of Variable Profile With the Help of a Grating

Abstract

A method of reducing circular parasitical polarization in the antennas of variable profile with the help of a grating of curved wires is reported. The experimental verification of the method shows that the parasitical signal practically vanishes. It was established that using this method, simultaneous observations at three or even five wavelengths can be made.
