Even so, this is pretty impressive, not all that long ago this device would be SF and people would doubt it would ever exist.
The antenna in mobile phones perform well across a wide range of frequencies due to being fractals!
A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously.
Is this inaccurate?
The associated electronics are obviously necessary too.
