Researchers have been pioneering antenna measurement methods for decades, but a new robot may be the ultimate innovation, extending measurements to higher frequencies while characterizing antennas ...
If you’ve ever worked at a station that’s installed a new antenna, you’ve probably wondered how well the antenna’s real pattern matched the nice clean pattern supplied by the antenna manufacturer. The ...
The ring down of the antennas is a huge bottleneck in spectroscopic measurements involving relaxation time (T2) measurements. The ring down of the antenna determines the dead time of the spectrometer.
Unmanned aerial vehicles — UAVs or “drones” — have been used for years by hobbyists and aircraft enthusiasts, but the field is now seeing rapidly expanding development in commercial applications. One ...
Anritsu Company extends its Electromagnetic Field (EMF) Measurement System with the introduction of isotropic antennas that provide frequency coverage from 9 kHz to 6 GHz. Compatible with certain LMR ...
Readers responded to my article comparing indoor TV antennas—some with questions, some just with comments (Comparing Antennas for Indoor Reception, September 2018). I welcome these as they give me a ...
While the subject of antenna measurements was discussed in a past column, questions still remain concerning what should be done, what it means and how they should be performed. Measuring the UHF TV ...
Danish startup QuadSAT uses specially equipped quadcopter drones as satellite stand-ins to help antenna makers and their customers test and calibrate antennas. Credit: QuadSAT TAMPA, Fla. — An antenna ...
Researchers continue to develop new antenna measurement methods, this time for future 5G wireless communications systems. Researchers at the National Institute of Standards and Technology (NIST) ...
