Abstract: A multi-tone measurement method for active phased array antennas (PAAs) operating in sub-6 GHz is proposed in a cost-effective, compact multi-probe over-the-air (OTA) chamber. Using our ...
Abstract: The article introduces a novel four-coil probe designed for eddy current (EC) nondestructive testing (NDT) on conductive materials. The key innovation lies in its capability to identify ...
