Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor to ...

Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a need to measure the associated electromagnetic field ...

In our previous column we discussed Ron Schacht’s inexpensive EAS receiver idea. Now I hear from Ken Beckwith that he is building and selling antennas to feed your EAS receiver. We shared a ...

The author is vice president of business development for Orban Labs Inc. Over the last 20 years or so, I have put in several FM master antenna systems in various broadcast facilities, to drive ...

An international team of physicists has created what might seem like a contradiction in terms: a non-radiating source of electromagnetism. By placing antennas inside a hollow dielectric disc, the ...

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.

Paper 403: Measuring magnetic loop antenna performance. Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a ...

There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull in some ...
