Apparatuses, methods, and systems for calibrating an antenna array are disclosed. One method includes selecting an antenna element of a first antenna subarray and an antenna element of a second antenna subarray, transmitting the signal through the at least one antenna element of the first subarray having a first selected phase, transmitting the signal through the at least one antenna element of the second subarray having a second selected phase, and characterizing a relative phase offset between the antenna element of the first antenna subarray and the antenna element of the second antenna subarray, including adjusting the first selected phase or the second selected phase, and monitoring a receive signal received at a calibration antenna that includes the transmitted signal of the at least one antenna element of the first antenna subarray and the transmitted signal of the at least one antenna element of second antenna subarray.
