Abstract
A method for enabling confirmation of expected phase shifts of radio frequency (RF) signals emitted from respective elements of an antenna array, such as a phased array antenna used for providing directional RF signal radiation patterns needed for beamforming. As a RF signal transmitted via an antenna element of the antenna array is shifted, e.g., stepped, in phase, the resulting received RF signal is monitored. Following detection of a phase shift, a sample of the received RF signal is captured and stored, e.g., for subsequent analysis, such as comparison with one or more expected signal phase differences to characterize the directivity of the transmitted signal.
