Engineers might design a fabulous new wireless device only to fall into the trap of poor antenna design or placement. I've heard stories about designers who place GPS-receiver antennas in metal boxes, ...

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 ...

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 ...

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) ...

StarLab is a near-field multi-sample system with spherical geometry. Antenna radiation patterns in the far field are obtained indirectly by sampling the field near the antenna. The sampled near field ...
