Abstract
A calibration system includes a beamformer lattice including at least a first beamformer, the first beamformer corresponding to a first subset of antenna cells of a plurality of antenna cells including a plurality of feed lines extending between the first beamformer and each of the first subset of antenna cells, and the first beamformer including a first calibration section for comparing a reference signal to a non-reference signal; and a first calibration line corresponding with the first beamformer, wherein the first calibration line is configured to deliver a first reference signal (mTx) from the first beamformer to be received by a first antenna feed line for comparison with a first non-reference signal (Rx) in the first beamformer, and/or wherein the first calibration line is configured to deliver a second non-reference signal (Tx) from a second antenna feed line for comparison with a second reference signal (mRx) in the first beamformer.
