The idea of a loop antenna is simple enough. It’s an inductor intended to respond to the magnetic portion of ... resonance by an air-spaced variable capacitor. Coaxial loops like this one ...

We don’t know if [OH8STN] has a military background, but we suspect he might since his recent post is about a “DIY Man Portable Magnetic Loop Antenna.” “Man-portable” is usually a ...

These antennas have moderate inherent directivity, but arrays can be better tuned for specific directions. Loop antennas have radiation patterns that are omnidirectional, and a small antenna with a ...

Theoretically, frequency independent (FI) antennas have near-field and far-field characteristics independent of frequency. Thus, an FI antenna must have an infinitely large aperture to eliminate the ...
