Abstract: Aspects of this disclosure relate to an array calibration system and method using probes disposed between antenna elements. In certain embodiments, the calibration is performed by measuring near-field relative phase and amplitude measurements of the antenna elements and using such relative measurements to adjust the amplitude and phase of the transceivers connected to the antenna elements. In some embodiments, each antenna element within a set of antenna elements transmits a signal that is received by a single probe, and the received signals are assessed to determine relative phase or amplitude measurements. In some embodiments, a single probe transmits a signal that is received by each antenna element within a set of antenna elements, and the received signals are assessed to determine relative phase and amplitude measurements.
