Millimeter-Wave Near-Field Measurements Using Coordinated Robotics

December 1, 2015
Author(s)
Joshua A. Gordon, David R. Novotny, Ronald C. Wittmann, Michael H. Francis, Miranda L. Butler, Jeffrey R. Guerrieri
The National Institute of Standards and Technology(NIST) recently developed a new robotic scanning system for performing near-field measurements at millimeter-wave (mm-wave)frequencies above 100 GHz, the configurable robotic millimeterwave antenna (CROMMA)

Millimeter-Wave Near-Field Measurements Using Coordinated Robotics

Joshua A. Gordon, David R. Novotny, Michael H. Francis, Ronald C. Wittmann, Alexandra Curtin, Miranda L. Butler, Jeffrey R. Guerrieri
The National Institute of Standards and Tech- nology (NIST) recently developed a new robotic scan- ning system for performing near-field measurements at millimeter-wave frequencies above 100 GHz, the CROMMA (Configurable Robotic Millimeter-Wave Antenna)

A Single-Pixel Touchless Laser Tracker Probe

October 15, 2015

Josh Gordon, David R. Novotny, Alexandra Curtin
We have developed a laser tracker probe, the Pixel Probe, that does not require physically contacting the object one is measuring and which has 3D spatial resolution of about 25 μm (in x,y,z) in the current configuration. This touchless laser tracker probe

Antenna Measurement Implementations and Dynamic Positional Validation Using a Six Axis Robot

October 11, 2015
Author(s)
David R. Novotny, Josh Gordon, Michael H. Francis, Ronald C. Wittmann, Alexandra Curtin, Jeffrey R. Guerrieri
We have performed spherical and extrapolation scans of two antennas at 118 GHz using a commercial 6-axis robot. Unlike spherical scanning, linear extrapolations do not precisely conform to the native circular movement of the individual robot axes. To

Generalized Probe-Position Compensation Methods for Near-Field Antenna Measurements

October 10, 2015
Author(s)
Michael H. Francis, Ronald C. Wittmann, Josh Gordon, David R. Novotny
The National Institute of Standards and Technology (NIST) has developed computationally efficient algorithms for probe location and polarization compensation in near- to far-field transformations for use when measurements are not made on the standard

Robotic Spherical Near-Field Measurements at 183 GHz

July 21, 2015
Author(s)
Michael H. Francis, Ronald C. Wittmann, David R. Novotny, Joshua A. Gordon
We describe millimeter-wave near-field measurements made with the new National Institute of Standards and Technology (NIST) robotic scanning system. This system is designed for high-frequency performance, is capable of scanning in multiple configurations

Configurable Robotic Millimeter-Wave Antenna Facility

April 13, 2015
Author(s)
Jeffrey R. Guerrieri, Joshua A. Gordon, David R. Novotny, Michael H. Francis, Ronald C. Wittmann, Miranda L. Butler
This paper introduces the Configurable Robotic Millimeter-Wave Antenna (CROMMA) facility by the Antenna Metrology Lab at the National Institute of Standards and Technology (NIST). NIST set out to develop an antenna measurement facility that would be
