How To Measure All Types Of Antennas Using Very-Near-Field Measurement

By Ruska Patton, Director, Product Management and Ning Yang, Principal Antenna Engineer, EMScan

In order to help avoid sending antennas that fail to meet specified design criteria, regulatory requirements, or consumer satisfaction to the marketplace, designers need to characterize the antenna to meet all of the performance criteria. Traditional characterization requires far-field testing or gathering near-field data sets to project field patterns. Unfortunately, the fastest and least costly near- or far-field techniques only generate reliable results for directional antennas. This article presents a novel very-near-field technology based on a probe array samples the AUT on a plane surface at a distance of 2.5 cm that can be used as an antenna measurement. Download the full article for more in-depth information on this technique.
