Abstract
An antenna, or in the context of an array an antenna element, includes a feed and a separate polarization converting director. The polarization converting director includes a helically disposed conductor defining a pitch, a projected diameter, and a longitudinal axis. The feed propagates electromagnetic radiation (in transmit mode) toward the director, parallel its axis. The director intercepts part of the radiation, focuses or directs the radiation, and also converts circular polarization to linear, or linear polarization to circular. The feed may thus be linearly or circularly polarized. Various feeds include waveguides or horns, slots, dipoles, and planar or nonplanar spirals.
