Abstract : The patent describes a disc on rod antenna radiating elements having bifilar helix feeds arranged in a particular concentric circle type array configuration to achieve high gain, improved elipticity and size and weight economies. Element spacing is adjusted to prevent element collecting aperture overlap. A collapsible segmented dielectric rod in combination with ring members of radial wire segments are utilized to provide an unfurlable array in one preferred embodiment.
