Antenna array module and measurement method thereof

Abstract

An antenna array module and a measurement method thereof are disclosed. The antenna array module includes a plurality of antenna elements, among which a subset is selected as eigen antennas for measurement. The method comprises: determining boundary conditions of the antenna elements; classifying the elements with the same boundary conditions into groups; selecting one representative element from each group as an eigen antenna; and measuring radiation performance of the eigen antennas. Measurement data of the eigen antennas is extrapolated to simulate the performance of non-measured antenna elements, thereby forming the overall array performance. Eigen antennas are provided with feeding interfaces that leave probe traces after testing, while non-eigen antennas omit such interfaces and remain without traces.
