Antenna Element Catalog

Fractal antennas use self similar designs to maximize the length, or increase the perimeter of material that can receive or transmit electromagnetic radiation within a given total surface area or volume. Fractal antennas are printed structures that is they are etched on a dielectric substrate.

The main advantage of fractal antennas are:

Reduced space requirement because of the compact size.
Higher input resistance because of increase in length or perimeter.

Multiband Nature and Miniaturization of Fractal Antennas

Analyze the multi band characteristics of fractal antennas and compare the size of fractal antennas with conventional antennas. The term fractal means irregular fragment. A Fractal is a rough or fragmented geometric shape that can be subdivided in parts, each of which is a reduced size of the whole. Fractal geometries are applied to antenna elements which aids in creating antennas of compact size and multi band behavior. These characteristics are required in small and complex circuits. Fractal antennas are multiband, high gain, low profile antennas. They are compact relative to the conventional antennas because of their efficient space filling nature.
