Millimeter-Wave Near-Field Measurements Using Coordinated Robotics

October 29, 2015
Author(s)
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)

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

October 11, 2015

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

Consensus Value Method to Compile On-Axis Gain Measurement Results

October 10, 2015

Jeffrey R. Guerrieri, Michael H. Francis, Ronald C. Wittmann
This paper shows that a consensus value method can be used to compile on-axis gain measurement data that have a large range of values and uncertainties. A variety of methods are used to analyze multiple data sets such as un-weighted averages, weighted

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

Widebend CTL cell to measure operating range of UHF RFID

March 5, 2015
Author(s)
Jehoon Yun, YongChae Jeong, David R. Novotny, Jeffrey R. Guerrieri
A wideband coupled transmission line (CTL) cell to measure the operating range of an UHF RFID (ORUR) is presented. Also, an ORUR test system is proposed to increase the isolation to more than 55 dB. It is shown that the ORUR measured by this proposed cell

INTERNATIONAL COMPARISON OF KU-BAND STANDARD GAIN HORN CHARACTERIZATION

April 11, 2014
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Michael H. Francis, Jason B. Coder, Joshua A. Gordon
International comparison of antenna measurement results between national measurement laboratories supports interoperability of communication equipment in today’s world market. The National Institute of Standards and Technology (NIST) is the pilot National

On the Use of Phase Data When Conducting an Extrapolation Measurement

November 1, 2013
Author(s)
Jason B. Coder, David R. Novotny, Michael H. Francis, Jeffrey R. Guerrieri
The extrapolation measurement technique has been used with the three antenna method for more than 40 years, to determine absolute antenna gain and polarization data. The critical part of the extrapolation technique is an insertion loss measurement that is

Using a Laser Tracker to Actively Coordinate the Motion of a 3m Industrial Robot to Within 50 Microns: An ongoing effort to accurately determine and correct positioning errors.

October 1, 2013

David R. Novotny, Joshua A. Gordon, Jason B. Coder, Jeffrey R. Guerrieri, Michael H. Francis
We are using industrial-grade robotics guided by a metrology-grade laser tracker to perform antenna calibrations at mmWave frequencies. We are using a 3 m-reach robot to spherically scan a milli-meter Wave (mmWave) probe around an antenna under test (AUT)
