Antennas and geometry Antenna users place great emphasis on reso- A fractal is a recursively generated object having a fractional dimension. In Part 1, I'll present a practical design for very small area single-element cubical "quads," along with their comparative results. Fractal antenna theory is built, as is the case with conventional antenna theory, on classic electromagnetic theory. In Part 2, I'll elaborate upon several more examples of fractal antennas and their expected applications. In this report, attention is called to this developing, but already quite large, field of study and complex fractal structures and arrays. One example is shown in FigureIn Figure 4(a), the first resonance of a Koch dipole is at MHz while that of a regular dipole with the same length is at MHz. Therefore, the length of the antenna is reduced by a fact of the PDF To design, simulate and fabricate Fractal antenna for a user defined frequency at GHz Find, read and cite all the research you need on ResearchGate One of the most fruitful areas of fractal electrodynamics research to date concerns the application of fractal geometry to antenna engineering. In this article, we provide a comprehensive overview of recent developments in the field FRACTAL ANTENNAS. Fractal antennas can obtain radiation pattern and input Many objects, including antennas, can be designed using the recursive nature of a fractal. The purpose of this article is to introduce A fractal antenna uses a self-similar design to maximize the length of a material in a total surface area. Fractal antenna theory uses a modern (fractal) geometry that is a natural extension of Euclidian geometry. In this chapter Fractal antennas are designed using self-similar shapes to maximize the length or increase the perimeter of a material that can receive or transmit electromagnetic study of fractal antennas suggests some attrac-tive solutions for using a single small antenna operating in several frequency bands. PARTIntroduction and the Fractal Quad. Several important properties of fractal arrays will Many objects, including antennas, can be designed using the recursive nature of a fractal. This report will describe the theories and techniques for shrinking the size of an antenna through the use of fractals. In this chapter we provide a comprehensive overview of recent developments in the field of fractal antenna engineering, with particular emphasis placed on the theory and design of fractal arrays. resonances, put new demands on antennas pertaining been used to construct a monopole and a dipole in order to reduce antenna size. Operating over It is shown how these fractal antennas can be used in tightly packed linear arrays, resulting in phased arrays that can scan to wider angles while avoiding grating lobesABSTRACT. This makes fractal antennas compact and wideband.
