1. A phased array antenna calibration system, comprising:
a radio frequency (RF) probe configured to transmit and receive an RF signal;
a probe layer coupled to the RF probe via a transmission line layer and configured to transmit or receive the RF signal with the RF probe, the probe layer comprising a plurality of probe elements arranged in an array that corresponds to an arrangement of radiating elements in an antenna-under-test (AUT), the plurality of probe elements in a one-to-one correspondence with the arrangement of radiating elements in the AUT, and each of the plurality of probe elements comprises a dimension and configuration to each corresponding the radiating elements in the AUT; and
a foam layer coupled to the probe layer and configured to separate the AUT from the probe layer.
