Popis:	A technique is presented for generating high quality circularly polarized radiation from an array of spiral elements by applying a mechanical rotation and a compensating electric phase shift to each element so as to steer the cross-polarized pattern into the grating lobe region. The technique is illustrated by simulations and measurements on a linear four-spiral array.
