/Antenna System Architecture With Calibration Feedback Routing For Per Element Calibration With Digital Beamformer
Abstract

A system may include multiple digital beamformer (DBF) circuits coupled to an analog front end that includes an antenna array. Each DBF circuit is coupled to a subset of the antenna elements of the array. Each DBF may be configured to adjust coefficients of complex multipliers to selectively enable and disable beams, antenna elements, transmit paths, receive paths, or any combination thereof to enable per-element calibration of the antenna array.
