  • Patent number: 11539146
    Abstract: A phased array antenna comprising: a substrate; a plurality of circular polarized wideband antenna elements disposed on the substrate, wherein each element comprises two orthogonal feeds; wherein the plurality of elements are organized into subarrays and physically oriented such that constituent elements of each subarray are sequentially rotated with respect to each other about respective axes that are perpendicular to a surface of the substrate so as to allow RHCP and LHCP transmission and reception; a phase shifter communicatively coupled to the feeds of all the elements and configured to electronically any dynamically compensate for phase regression or progression introduced by the sequential rotation of the elements without relying on physical transmission lines of different dimensions, and further configured to introduce a progressive phase shift across a beam steering plane to enable beam steering of the phased array antenna.
