Indeed! The antenna in mobile phones perform well across a wide range of frequencies due to being fractals! https://en.wikipedia.org/wiki/Fractal_antenna http

  No, it does so because of solid state tuners, and RF switches.

    The article I linked claims: 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.

      Fractal antennas are mostly snake oil. You’ll always see then driven against a large counterpoise (ground plane), as the counterpoise becomes the radiator. You can make use of Chu’s limit without resorting to fractals. https://en.m.wikipedia.org/wiki/Chu–Harrington_limit https://en.m.wikipedia.org/wiki/Chu–Harrington_limit

        FYI @madengr, almost all of your recent comments - going back a few months, are in [dead] state. Not sure if you've been shadow-banned or what, but you might want to contact the mods or something.

          Ha ha, yes I have been shadow banned for several months.
