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 ...
