Abstract
Disclosed is an anechoic test chamber that includes six antenna probes, replacing a single probe with a small array, and using the array to form a beam to provide a similar signal to the probe signal, and reducing the transmission loss. At least five of the probes are aligned in the anechoic chamber such that the probes are aligned in azimuth along four columns separated from a center point by +/−5 degrees and +/−15 degrees. The probes are further aligned in elevation along three rows at the center point and separated from the center point by +/−5 degrees, wherein the alignments in azimuth and elevation are within 3 degrees measured spherically of the alignments stated. Also disclosed is a planar array that replaces probe antennas and forms beams to provide coverage to the chamber, and utilizing probe arrays to emulate base station signals to evaluate UE performance.
