Claim Text:
1. A system comprising: an array of fragmented aperture antenna elements, wherein each fragmented aperture antenna element of the array comprises: a plurality of subcircuits responsive to commands to adjust first and second RF signals communicated with the first and the second feeds respectively of each of the fragmented aperture antenna elements of the array; and a digital control to provide the commands to the subcircuits, wherein the provided commands are used by the subcircuits to scan a beam of the adjusted RF signals to a particular scan angle by adjusting the first and the second RF signals of each fragmented aperture antenna element relative to the first and the second RF signals of other fragmented aperture antenna elements of the array, and to compensate for cross-polarization in the beam due to the particular scan angle by adjusting the first RF signal relative to the second RF signal of each fragmented aperture antenna element.
