Abstract

In this paper, over-the-air (OTA) phase measurement and calibration method for a fifth generation (5G) millimeter wave radio frequency unit is presented. The phase error measurements are done for both receiver and transmitter. The measurement results are used to calibrate the individual antenna ports of the antenna array system so that accurate radiation patterns can be formed. In order to confirm the calibration, the radiation patterns are measured with a 100 MHz wide 28 GHz 5G New Radio communication signal. The measurements show that the calibration improves the maximum power level flatness of radiation patterns and reduces side lobe levels.
