Phased arrays of helical and zigzag-antennas
Abstract
Phased arrays of helical and zigzag-antennas are treated that are circularly mounted above a total reflecting plane. The farfield characteristics are calculated by the method of moments with regard to the radiation coupling between the single antennas. An optimization technique yields farfield diagrams with small mainlobes and very low sidelobes. The mainlobe is scanned in the hemisphere by steering with variable phases.
