IEEE EMC-S PL reported activity no. 10/2024: Distinguished Lecture by Benoit Derat “Talk 1: How Close Can Far-Field Be? Getting the Best Out of Your Measurement Range”
Talk 1: How Close Can Far-Field Be? Getting the Best Out of Your Measurement Range
Trends in modern wireless communications, including the use of massive MIMO and millimeter wave frequencies, have supported an increased deployment of electrically large antennas. This created technical and economic challenges as many EMC or regulatory tests require a far-field condition. This talk provides an overview of the recent findings in defining the shortest possible far-field test distance, depending on the size of the device under test, its operation frequency, the target metric and the upper bound acceptable measurement deviation. Practical ways are also described to determine the maximum antenna aperture size that can be tested in the far-field at a given frequency and for a maximum error, in an existing chamber with a defined range length.
