Abstract
Systems and methods for beamforming using a cross-mixing architecture are provided. A beamformer can use an element-to-element mixing concept and can avoid the use of conventional bulky analog phase shifters. Incident signals can be sent through a phase-locked loop and then mixed with a signal from an antenna element oppositely spaced about a phase center of the antenna element array. Beamformers can be integrated into existing hybrid structures by substituting the traditional analog part of the beamforming process.
