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 ...

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 ...

The National Institute of Standards and Technology (NIST) has created a robotic arm that is being used to measure the properties of antennas rapidly and accurately. The robot, formally named the ...

The smartphone antenna’s poor multipath suppression and irregular gain pattern result in large time-correlated phase errors that significantly increase the time to integer ambiguity resolution as ...

GPS IS VIRTUALLY UBIQUITOUS with more than 400 million units estimated to be in use in the United States alone. Some of these units are standalone devices such as those used in surveying and timing ...
