The 1ST section is ¡°Introduction¡±.
In this paper, we study the calibration technology for fully active mmWave phased array antennas.
Then, the Self-developed 1x8 array antenna module is calibrated by the SDR platform.
Next, the initiating calibration uses rotating element electric field vector (REV1) algorithms.
Next, we propose a technique to strengthen the synthesis of vectors and overcome the ambiguity problem of REV.
Moreover, we propose the incrementally joint block tuning of subarrays to enhance the REV method for large array antenna calibration.
