Title:
METHOD, APPARATUS AND SYSTEM FOR MEASURING TOTAL RADIATED POWER OF ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/214570
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present invention are a method, apparatus and system for measuring the Total Radiated Power (TRP) of an array antenna. The method comprises: determining the Rayleigh resolution of an array antenna in an angle space, and setting a stepping grid pitch of a sampling point according to the Rayleigh resolution; determining the sampling point according to the stepping grid pitch, measuring the equivalent isotropically radiated power (EIRP) at the position of the sampling point, and determining the TRP according to the EIRP. According to the embodiments of the present invention, measurement errors with respect to a conventional testing mode using angular stepping grids θgrid and φgrid of 15° are reduced; in addition, by means of normalized space transformation of wave vectors, the number of sampling points is further reduced, and the measuring efficiency is improved.
