Title:
ANTENNA TESTING SYSTEM AND ANTENNA ARRAY TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/198956
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are an antenna testing system and an antenna array testing method, used to improve antenna array testing flexibility. The antenna testing system of embodiments of the present application comprises: a testing antenna array, an antenna array under test and an analysis processing module; the antenna array under test comprises a number N of first array elements, the testing antenna array comprises N second array elements, the N first array elements and the N second array elements corresponds one-to-one, and N is an integer greater than 1; the antenna array under test is used to send a first testing signal by means of a first array element to a second array element; the testing antenna array is used to receive the first testing signal sent by the first array element by means of the second array element; the analysis processing module is used to determine an uplink radio frequency indicator of the first array element according to the first testing signal; the analysis processing module also is used to determine an uplink synthetic radio frequency indicator of the antenna array under test according to the uplink radio frequency indicator of each first array element in the antenna array under test.
