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 ...

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 ...

FAIR principles are increasingly being adopted within the field of antennas and propagation to ensure that data is findable, accessible, interoperable and ...

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 ...

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 ...

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 ...

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 ...

Fernando Las-Heras received the M.S. degree in 1987 and the Ph.D. degree in 1990, both in Telecommunication Engineering, from the Universidad Politcnica de Madrid (UPM), Spain. Since 1991 he has held ...

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 ...

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.
