Fractal Antennas

There has been an ever-growing demand, in both the military as well as the commercial sectors, for antenna designs that possess the following highly desirable attributes: 1. Compact size 2. Low profile 3. Conformal 4. Multi-band or broadband

There are a variety of approaches that have been developed over the years, which can be utilized to achieve one or more of these design objectives. Recently, the possibility of developing antenna designs that exploit in some way the properties of fractals to achieve these goals, at le ....etc

A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic radiation within a given total surface area or volume.

Such fractal antennas are also referred to as multilevel and space filling curves, but the key aspect lies in their repetition of a motif over two or more scale sizes, or iterations. For this reason, fractal antennas are very compact, multiband or wideband, and ha ....etc

ABSTRACT
A detailed study on the various next generation nature inspired geometry antennas
i.e. fractal antennas is performed. Mainly four types of printed fractal antennas i.e.
Sierpinski Carpet, Quasi Koch Fractal, Mix fractal and Sierpinski Gasket Fractal
are designed using 3D FEM based solver (Ansoft HFSS), which are basically
variants of Patch antenna. Maximum iteration is three and these antennas are fed
using three basic techniques Transformer Feed, Inset Feed and ....etc

Small Fractal Antennas

1 Problem
Antennas for hand-held communication devices are necessarily small, and typically use wavelengths
that are large compared to the size of the antenna. This typically implies that
the magnitude of the antenna reactance X (= imaginary part of the antenna impedance) is
large compared to that of its radiation resistance Rrad (which is related to the time-average
radiated power P and the peak current I0 at the feedpoint by P = I2
0Rrad/2), so that it is
challenging to build an effective imped ....etc

Abstract
Wireless applications, particularly with multiple resonances, put new demands on antennas pertaining to size, gain, efficiency, bandwidth, and more. One promising approach in this regard is to use fractal geometries to find the best distribution of currents within a volume to meet a par ....etc
