A research team has built a Hall rectenna based on the type-II Weyl semimetal NbIrTe4 that, according to a study in Nature ...

Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets. The smallest ...

This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...

Small ceramic patch elements offer nearly perfect single-frequency receive characteristics and have become the standard for GPS L1 antennas. However, the new generation of GNSS receivers now being ...

In recent columns, I've discussed options for TV-transmitting antennas. This month, I'll look at the other end of the path – outdoor TV-receiving antennas. I'll describe desirable attributes for DTV ...

Isolation refers to keeping multiple antennas separate from one another to avoid interaction effects. In some devices—especially cell phones, where multiple antennas must be squeezed into a small ...

This article was written by Louis Frenzel, author of Principles of Electronic Communications Systems, that addresses this topic and much more. Antennas are much more than simple devices connected to ...

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 ...
