 For this reason, fractal antennas are very compact, multiband or wideband, and have useful applications in cellular telephone and microwave communications.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.Normally standard antennas have to be "cut" for the frequency for which they are to be used—and thus the standard antennas only work well at that frequency.
