They can have an unlimited number of shapes and sizes, but can transmit/receive in almost any polarization. These antennas have moderate inherent directivity, but arrays can be better tuned for ...

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 ...
