This invention provides a method of creating ultra wideband high gain fractal antennas. The method is based on applying of fractalization rules (regular or irregular shapes) on known microstrip and (or) slotted radiators. Fractalization term was first used from Benoit Mandelbrot. Until now several regular shapes are known—Koch Island, Sierpinski gasket, Cantor Set, Minkovski island etc. and several irregular as Fractal tree, Fractal Snowflake, Koch curve, Minkovsky curve, etc.
The prior art planar antenna with aperture (2) is cut in conductive layer (1) and has feed (3) is shown at
All the antennas shown are scaled to 87 mm×72 mm cooper cut using 1.6 mm FR4 substrate material.
The current invention is an apparatus including the fractal aperture, feed and reflector for improving the gain. The feed (3) is located in a planar layer with the aperture (2) cut in a conductive layer (1) regarding
