Abstract

One or more fractal antennas are produced in an electroforming circuit. A stainless steel on glass mandrel is covered with a dielectric in an inverse image of a fractal antenna to be formed. The portion of the stainless steel uncovered by the dielectric is chemically washed so that a fractal antenna formed thereon can be more efficiently removed. The mandrel is made a cathode in an electroforming circuit, which results in a fractal antenna being formed on the mandrel. The fractal antenna is separated from the mandrel and mounted on a rigid or semi-rigid substrate.
