Abstract
The performance of millimeter-wave (mmWave) radio systems depends on accurate knowledge of mmWave phased array multi-beam patterns. However, the conventional antenna pattern measurement methods are inefficient for mmWave multibeam measurements. To solve the problem, a fast multi-beam reconstruction method has been proposed in the literature. Based on that, this paper conducts an efficient multi-beam pattern measurement campaign for a practical 4 × 4 mmWave phased array antenna-in-package (AiP). The measurement results show that the element patterns of an active phased array AiP measured in the on-off and all-on modes might differ, especially for large-scale arrays. Furthermore, the reconstructed array multi-beam patterns by the proposed method are compared with the conventional compact antenna testing range (CATR) measurement data. The all-on reconstructed array multi-beam patterns matches better with the target array patterns than the on-off reconstructed array patterns.
