At UCLA, they're using fractals (a matchematical way to model coastlines, mountains and other natural landscapes) to design wireless antennas.

Fractals, short for "fractional dimension," are mathematical models originally used to measure jagged contours such as coastlines. Like a mountain range whose profile appears equally craggy when observed from both far and near, fractals are used to define curves and surfaces, independent of their scale. Any portion of the curve, when enlarged, appears identical to the whole curve — a property known as "self-symmetry."

Using fractals may allow 'more' antenna length to be packed into spaces.
