Beam steering a quadrifilar helix antenna at S-band using a monopole

Abstract

In this paper, an alternative approach to beam steering is presented through the use of a novel quadrifilar helix antenna, with a monopole in its center to get a low form factor and high performance. By altering the phase and amplitude of the monopole, the beam can be `steered' 360 degrees in the phi direction, and 90 degrees in the theta direction. Simulated test data showing antenna performance will be compared to current beam steering methodologies.
