Abstract
An antenna for transmitting electromagnetic radiation. The antenna comprises a core further comprising at least one layer of contiguous core material and windings disposed on the core forming a plurality or winding segments. The windings define gaps between each winding segment, wherein parameters of the gaps and parameters of the windings are selected to generate a balanced magnetic field. A material of the core comprises an amorphous or annealed material, further comprising metal or alloys, comprising one or more of nickel or nano-crystalline or nano-materials.
