They have unique characteristics based on geometry and design of fractals. They have various applications which include image compression lightning etc.

### Other non-regular or mathematical generated fractal curves was investigated for fractal.

**Fractal antenna applications**. This book is downloadable in PDF ePub Kindle and TXT format. First they can improve the performance of antenna or antenna arrays. 2 self-filling reduces the overall dimension and is useful for the design of small antennas such as.

The fractal geometry based shapes have been found in the nature. Fractal Antenna Applications 353 The fractal design of antennas and arrays results from applying the new fractal geometry in the context of electromagnetic theory. Show full abstract applications.

Smaller dimension an antenna that covers multiple applications using a single device and therefore efforts are being made to concentrate more on the fractal antenna structure 1The word fractal comes from latinfractus which means broken lines. Fractal geometry is using iterative process. Fractal Antennas for Wearable Applications Mohamed I.

Not all fractal shapes are best suited for antennas. Fractal Antennas APPLICATIONS The geometry of the fractal antenna encourages its study both as a multiband solution and also as a small physical size antenna. Available in PDF ePub and Kindle.

Sierpinski triangle Example of fractal antenna. A wearable antenna is intended to be a part of clothing used for. On fractal geometry the fractal antennas appears as natural way to explore for multi-frequency operation and for an antenna size reduction.

The antenna achieved the GSM UMTS and HiperLan frequency with -6 dB return loss and has almost omnidirectional radiation pattern. Additionally fractal antennas do not require additional components assuming the structure happens to have the desired resonant input impedance. High radiation efficiency high gain wide bandwidth and reduced size etc.

Not all fractal antennas are ideal for certain applications. Use in cellular phones and military communication hardware. A simple design methodology based on the self transformation property of.

Free download of Fractal Antenna Applications by Mircea V. This book discusses the use of fractals which are geometric shapes that repeat itself over a variety of scale sizes so the shape looks the same viewed at different scales as design for antennas. A fractal antenna is an antenna that uses a fractal self-similar design to maximize the effective 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.

Fractal antennas are designed to be used for multiple frequency bands and applications. Antenna designers are always looking to come up with new ideas to push the envelope for antennas using a smaller volume while striving for every higher bandwidth and antenna gain. As a result of the works carried out so far you can point to the benefits of using the fractal antenna technology.

Ahmed and Mai F. Fractal Antenna for multiband applications has a better performance than others. Koch curve fractal antenna.

Read write reviews and more. The antennas suitability for a particular application can be determined by RF testing and computer search methods. FRACTAL SHAPED ANTENNA ELEMENTS FOR WIDE- AND MULTI- BAND WIRELESS APPLICATIONS A Thesis in Engineering Science and Mechanics by KJ.

They can be ¼ the size of the regular ones. The application of our fractal technology minimizes antenna form factors often both size and weight. IVCONCLUSION Fractal-like geometrical structures with self transformation property have been investigated for multiband communications antenna applications.

This is just a preview of the first few pages. First because one should expect a self – similar antenna which contains many copies of itself at several scales to operat e in a. Ahmed Abstract This chapter focuses on the design and fabrication of different types of flexible and inflexible wearable fractal for modern wireless applications with body-area-networks BANs.

Fractal antennas are a fairly new research area and are likely to have a promising future in many applications. 1 self-similarity is useful in the design of the antenna working on multiple frequencies for example the Sierpinski triangle fractal tree and the Cantor set. A fractal is a fragmented or split geometric shape that can be subdivided into parts.

Fractal geometries have been introduced for antenna applications with varying degrees of success in improving antenna characteristics. One proposed method of increasing bandwidth or shrinking antenna size is via the use of fractal geometry which gives rise to fractal antennas. Fractal antennas have more benefits such as.

Each of this is a reduced-size copy of the whole. The obtained frequency bands are X- band and Ku- band. II EXISTING DESIGN In this model 3 iterations of star shaped Koch fractal antenna were designed using HFSS V13 Simulation tool 0th Iterations Koch fractal antenna is labeled as I-0 with the.

Vinoy Submitted in Partial Fulfillment of the Requirements for the Degree of. Our smaller and less obtrusive form-factors give you maximum design flexibility better aesthetics and a lower likelihood of interaction with other antennas and electricals. How Fractals can be used as Antennas and why Fractals are Space-filling Geometries While Euclidean geometries are limited to points lines sheets and volumes fractals include the geometries that fall.

Fractal antennas can obtain radiation pattern and input impedance similar to a longer antenna yet take less area due to the many contours of the shape. Wideband performance Koch fractal antenna was chosenFractal antenna can be operated at 245 GHz in different wireless applications such as WLAN Wi-MAX Bluetooth etc3. The proposed fractal antenna can be operated in different frequencies and 2 frequency bands.

Fractal-shape antennas can respond to more frequencies than regular ones. Some of these geometries have been particularly. Fractals help in two ways.

Ahmad PJ Soh FMalek 3 proposed the fractal PIFAPlanar Inverted F Antenna with bandwidth enhancement for mobile phone applications. Rusu and Roman Baican. Generally fractals are self-similar and independent of scale.
