Antennas come in many shapes and sizes, with a variety of characteristics making them more or less suitable for various applications. The average hacker with only a middling exposure to RF may be ...

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 ...

Explore the fascinating comparison between magnetic fields produced by a current loop and electric fields generated by a dipole. This short breaks down key similarities and differences using clear ...

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 ...
