Are fractal antennas better?
Their advantages are good multiband performance, wide bandwidth, and small area. The gain with small size results from constructive interference with multiple current maxima, afforded by the electrically long structure in a small area. Some researchers have disputed that fractal antennas have superior performance.

If you live in an area with great over-the-air TV reception, a paper clip may be the first option you want to try. All you need to do is straighten out the paper clip and put it into the cable/antenna plug on your TV (that round connector you used to connect the cable outlet from your TV).

What Is a Bowtie Antenna? A bowtie antenna uses triangular elements instead of straight rods as the antenna elements. The triangular elements sticking out on both sides of the antenna resemble a bow tie, hence the name. The “wings” of the antenna flare out symmetrically on both sides of the supporting beam.

What makes fractal antennas different than regular antennas?
“Fractal antennas not only shrink antenna sizes, but also control multiband performance, enable wideband use, and actually increase realized gain in small sizes. The gain attribute arises from being able to produce multiple current maxima, such as on a fractal perimeter, in a highly compact area.
What are fractal antennas used for?
Fractal antennas have space-filling properties that can be used to miniaturize classic antenna elements and overcome some of the limitations of small antennas. Many fractal element antennas use the fractal structure as a virtual combination of capacitors and inductors.

FRACTAL ANTENNA
The original inspiration for the development of fractal geometry came largely from an in-depth study of the patterns of nature Figure (1) . The term “Fractal” means linguistically “broken” or “fractured” from the Latin “fractus.” This term was created by Benoît MANDELBROT 40 years ago in 1974 [3].

Abstract. Fractal behavior is scale-invariant and widely characterized by fractal dimension. However, the cor-respondence between them is that fractal behavior uniquely determines a fractal dimension while a fractal dimension can be related to many possible fractal behaviors.

The lungs
The lungs are an excellent example of a natural fractal organ. If you look at the tree upside-down (mouse over the image), you can see that the lungs share the same branching pattern as the trees. And it is for good reason! Both the trees and lungs have evolved to serve a similar function – respiration.
Why did phones used to have antennas?
In the early days of cellphones, the wavelength of carrier waves was typically about thirty centimeters, and so the first mobile phones relied on extractable antennas, similar to the ones used in handheld radios. As higher frequencies became available, wireless customers soon started reaping other rewards.

Can you use a TV antenna for a cell phone booster?
In most cases you can connect any antenna to a cell booster. Most home cell boosters use the same F-connector and RG6 cable as television antennas.
What is the purpose of a fractal?
A fractal is a recursively created never-ending pattern that is usually self-similar in nature. Separate from Euclidean geometry, fractal geometry addresses the more non-uniform shapes found in nature, such as mountains, clouds and trees. Fractals provide a systematic method to capture the “roughness” of some objects.

What is a fractal in simple terms?
A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems – the pictures of Chaos.
