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

Authors: Lars Jacob Foged, Ramakrishna Janaswamy, Vicente Rodriguez, Donald McPherson, Vikass Monebhurrun Publication: LACAP 2026 Copyright Owner: IEEE The IEEE Antennas and Propagation Society (AP-S) Standards Committee (SC) plays a central role in developing, maintaining, and promoting technical standards that support antenna terminology measurements and propagation, modeling practices, and other related topics. This paper provides an overview of current AP-S standardization activities, covering the status of active and emerging projects, the evolution of community engagement strategies, and the operational challenges facing volunteer-driven standards development. Recent outreach efforts, collaboration with related societies and the committee’s recognition program are also discussed. View the paper

Authors: Vince Rodriguez, Mark Ingerson, Gwenael Dun, Esra Celenk Publication: AMTA 2025 Copyright Owner: NSI-MI Technologies The first mention of a Robot for near-field measurements of antennas appears is by Jeff Snow in [1]. This was a simple robotic arm to do planar measurements. About 7 years later, the use of off-the-shelf industrial robotic arms for doing antenna measurements is introduced [2]. Since then, industrialrobot- arm based antenna measurement systems have become increasingly popular due to their flexibility to measure over different surfaces allowing the system to do planar, spherical and cylindrical. The use of other methods to perform the transform, by numerically compute the currents on an arbitrary surface from the measured fields has helped in the growing popularity of robotic systems. This is related that the measurement surface does no longer have to be a canonical surface but can be any shape. However, the flexibility of the robots may be limited by the RF absorber coverage used in treating them. In this paper, the authors explore the potential scattering from the robotic arm in different positions and its effect on the probe illuminations. This is an area of research on the use of absorber that has not been explored until recently [3]. Numerical experiments are conducted to explore the effects of RF absorbers in the 300 MHz to 3 GHz range. Open ended waveguides (OEWG) as well as dual ridged horns (see Figure 1) are used as the probes. The results suggest that some areas of the arm need to be treated while others can be left bare. The analyses performed suggest that optimized treatment of robotic arms to maintain the flexibility of the technique while also reducing effects on the probe illuminations are possible. View the paper
