When to Perform Antenna Measurements in a Near-Field Range or a Short Tapered Chamber

Abstract : This study was undertaken to quantify and compare electromagnetic device (i.e., antenna) measurements using the US Army Research Laboratorys (ARLs) near-field range and tapered anechoic chamber. Our 2 antenna measurement systems obtain similar results as reported in a previous ARL technical report, A Comparison of Antenna Measurements in a Near-Field Range and a Newly Renovated Short Tapered Chamber, but a decision tree is needed to obtain the results for future antennas under test in the most cost-effective manner (man-hours, custom mount, etc.)
