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 ...

Scientists bend, not break, the laws of physics. Faced with limitations imposed by physics, laboratory researchers are generating antenna innovations by tweaking constructs to change the rules of the ...

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 ...
