Line 77:
Tapers can be used to match a transmission line to an antenna. In some designs, such as the [[horn antenna]] and [[Vivaldi antenna]], the taper is itself the antenna. Horn antennae, like other tapers, are often linear, but the best match is obtained with an exponential curve. The Vivaldi antenna is a flat (slot) version of the exponential taper.<ref>{{multiref|Bakshi & Bakshi|pp. 3-68–3-70|Milligan, p. 513}}</ref>
=== Fractals ===
The use of [[fractal]] curves as a circuit component is an emerging field in distributed element circuits. Fractals have been used to make resonators for filters and antennae. One of the benefits of using fractals is their space-filling property, making them smaller than other designs. Other advantages include the ability to produce [[wide-band]] and [[Multi-band device|multi-band]] designs, good in-band performance, and good [[out-of-band]] rejection. In practice, a true fractal cannot be made because at each [[Iterated function system|fractal iteration]] the manufacturing tolerances become tighter and are eventually greater than the construction method can achieve. However, a small number of iterations, the performance is close to that of a true fractal.
