Authors: Vince Rodriguez, Mark Ingerson, Esra Çelenk and Gwenaël Dun Publication: AP-S/CNC-USNC-URSI 2026 Copyright Owner: IEEE Industrial-robot-arm based antenna measurement systems have become popular in recent years due to their flexibility to measure over different surfaces allowing the system to do planar, spherical and cylindrical, as well as non-canonical surfaces using newer methods to get the far field from calculated currents around the antenna under test (AUT). But their flexibility may be limited by the RF absorber coverage used. In this paper, the authors explore the potential scattering from the robotic arm in different positions and its effect on the probe illuminations. Numerical experiments are conducted to explore the need for RF absorbers at low frequencies in the UHF band. Results show that like in standard positioners, more absorbers are not necessary and for the UHF band, RF absorber coverage is not needed on the arm section closer to the probe. At higher frequencies, treatment of the second section of the arm may be required. View the paper

Author: Scott T. McBride Publication: AMTA 2025 Copyright Owner: NSI-MI Technologies The approach of non-redundant near-field sampling has been available for many years. A general and automated approach that yields the expected time reduction for an arbitrary antenna volume, however, has been elusive. One of the more practical approaches is the “PNF wide-mesh” sampling, where the probe grid is separable in x and y, and this approach is the one explored in this paper. A fundamental step in non-redundant sampling is to identify a volume that fully contains the AUT. Constraints imposed by theory have typically led this volume to be rotationally symmetric about a z-oriented line, and often also require that the volume be more spherical (less oblate) than a volume circumscribing the AUT. That larger volume generally results in more acquisition time than would a conformal volume, but allows those samples to be readily interpolated to the conventional half-wavelength PNF grid. This paper examines the impacts of relaxing those constraints in order to further reduce the required sampling time for a box-shaped AUT. It then looks for ways to reduce or remove those impacts. The implementation of this algorithm involved a minor reformulation, specific to the PNF (or linear-axis) geometry, of the underlying non-redundant sampling theory. That reformulation is briefly described herein. A new family of tunable AUT-volume edge treatments similar to the existing “double-bowl” is also described. The paper will show minor reductions in predicted acquisition time compared to non-redundant sampling with a circular double-bowl volume. Each non-redundant approach typically offers a 40-60% reduction with a rectangular AUT volume compared to a full conventional scan. A more notable advantage of the new approach is a significant reduction in preacquisition activity defining the several parameters that govern the non-redundant acquisition and processing.
