This work presents the design and comparison of three different types of printed helix antennas. Using multiple directors, the printed helix antennas radiate in the backfire direction resulting in Yagi-Helix antennas. This is a further step toward the Yagi-Helix antenna design, where the printed helix is used instead of the conventional one for more mechanical stability and reproducibility. The full wave simulation results of the three designs are presented and compared. Finally, the phase centre of each of the three antennas is presented to show the possibility of using these antennas as feeders for centre-fed paraboloid reflector antennas.
