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, ...

If you want to analyze an antenna, you can use simulation software or you can build an antenna and make measurements. [All Electroncs Channel] does both and show you how you can do it, too, in the ...

No audio available for this content. More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS ...

When [Jephthai] wanted to build his own Yagi antenna, he turned to MMANA software for antenna modeling. This is an antenna analysis program that uses the moment method to calculate parameters for ...

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 ...

QuadSAT, a Danish startup that uses drones for the test and measurement of satellite antennas, has scaled up its ambitions: it reports successfully completing a measurement campaign of large antennas ...

SwRI’s 1,260-square-foot indoor spherical near-field antenna range is equipped with a built-in overhead half-ton hoist to install and test large antennas up to 10 feet in diameter and 1,000 pounds.
