Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

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, ...

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 ...

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 ...

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) ...
