Abstract

This work proposes a noise figure (NF) measurement method for active antennas based on the over-the-air (OTA) method. First, the relevant concepts of NFs are reviewed. Then, the calibration of path gain is proposed and the calculation for the NF is deduced. Finally, the measurement setup and procedure are presented, and the measurements are performed. The results using the proposed method and those from traditional conduction measurement are compared, which verifies our idea. Compared to the existing methods, the proposed method has the advantage of independence on the measurement distance between the transmit antenna and the active antenna under test (AAUT) in a specified range.
