The mathematical absorber reflection suppression (MARS) technique has been used to identify and then suppress the effects of spurious scattering within spherical, cylindrical, and planar near-field antenna measurement systems, compact antenna test ra

Near-field antenna test systems are typically designed to optimize measurement results for a specific type of antenna. The measurement system is selected and sized based on the antenna aperture dimensions, directivity, weight and operating frequency,

Spherical near-field (SNF) antenna test systems offer unique advantages over other types of measurement configurations and have become increasingly popular as a result. To yield accurate far-field radiation patterns, it is critical that the rotators

A near-field measurement technique for the prediction of asymptotic far-field antenna patterns from data obtained from a modified cylindrical or plane-polar near-field measurement system is presented. This technique utilizes a simple change in facili

Spherical near-field measurements have become a common way to assess performance of a wide variety of antennas. Published reports on range error assessments for spherical near-field ranges however are not very common. This is likely due to the percei

Band limiting radiating fields from a finite sized field distribution has been shown to be a highly effective way to eliminate spurious scattered fields from antenna measurements [1, 2, 3]. These techniques have been used with impressive results in m
