US Patent 10468781 Polarization control for electronically scanned arrays

Systems and methods of controlling signal polarization are provided herein. An antenna array may include antenna elements each communicatively connected to a variable gain amplifier (VGA) with discrete amplitude control, and a phase shifter with discrete phase control, to provide discrete polarization states. A polarization controller may identify a target polarization state with a target amplitude and a target polarization angle. The polarization controller may identify a first polarization state and a second polarization state from the discrete polarization states, that are nearest in absolute amplitude to the target amplitude and nearest in polarization angle to the target polarization angle. The polarization controller may concurrently form a signal with the identified first polarization state using a first portion antenna elements, and a signal with the identified second polarization state using a second portion of antenna elements.
