A Comparison of Antenna Measurements in a Near-Field Range and a Newly Renovated Short-Tapered Chamber

Abstract

This study was undertaken to quantify and compare electromagnetic device (i.e., antenna) measurements using the US Army Research Laboratory's (ARL) near-field range (NFR) and tapered anechoic chamber, which has been newly renovated with absorber material. ARL would like to know the performance levels with the NFR and the newly renovated, slightly different absorber layout configuration laid out and designed by the contractor. Post-renovation measurements in the tapered chamber led to a further reconfiguration of the absorber near the apex. This second post-renovation reconfiguration resulted in a slight performance improvement over the initial post-renovation, but not as broadband as the pre-renovation data.
