Abstract
An antenna array controller is configured to measure a magnitude and phase of each of a set of antenna array elements, and compensate for leakage of other elements of the set of array elements. The leakage may be compensated for by one or more mechanisms including phase cancellation by row of antenna array elements, programmatic cancellation via a single offsetting antenna array element of the antenna array elements, and deembedding array leakage by subtracting the array leakage from the measured data.
