Abstract

A phased array antenna initial amplitude and phase detection method based on array beam scanning, which can perform black-box testing on millimeter wave phased array antennas, and has high calibration efficiency. The detection device includes: the phased array antenna to be tested, the probe antenna, the parameter measurement device, the DC power supply, and the control calculator. The phased array antenna to be tested, the probe antenna, and the parameter measurement device are placed in the dark room. Outside the dark room, the probe antenna is placed directly in front of the phased array antenna, the parameter measurement device is connected to the phased array antenna to be measured and the probe antenna, the DC power supply supplies power to the phased array antenna to be measured, and the control calculator is connected to the phased array antenna to be measured. ; Taking the parameter measurement device as the core, beamforming the entire array, measuring the transmission S parameters under a specific beam, and obtaining the calibration matrix C required for phased array calibration.

Description

technical field [0001] The present invention relates to the technical field of millimeter wave measurement and antenna performance test, in particular to a phased array antenna initial amplitude and phase detection method based on array beam scanning, which is mainly used for millimeter wave phased array antenna calibration. Background technique [0002] With the development of 5G mobile communication, the data rate and traffic carried in the communication system are increasing, and the sub6GHz and below frequency bands are facing the dilemma that the data carrying capacity cannot meet the needs. Since millimeter wave (mmWave) and higher frequency bands have greater available bandwidth and can carry a huge amount of traffic, they are attracting people's interest. At present, the millimeter wave system has been widely used in satellite communication, radar and 5G mobile communication. Among them, the millimeter-wave antenna system has a large bandwidth and can have a small p...
