Over-the-Air Calibration & Measurements
Over-the-air (OTA) calibration and measurements of mmWave active array antennas is perfromed by PAARD team. The measurement results are used to calibrate the individual antenna elements embedded in the finite array. Direct Far-field antenna patterns and indirect patterns are also obtained with Near-field planar scanner developed by OU-PAARD.
Projects
Over-the -air Antenna in Chip Calibration
This project is supported by Metwave to calibrate an 4x4x antenna on chip designed to operate at 77 GHz. FF over-the air method was used for calibration, and Near-field planar was used to validate the calibration procedure.
