An antenna for radiating toroidally is disclosed. The antenna may be fabricated to conform with any size of system. The antenna may be placed around an electronics package or a structure to radiate toroidally around the electronics package or structure. The antenna is formed of a strip of copper which includes a number of slots. The slots are disposed longitudinally within the strip of copper such that, upon the application of power to the copper strip, the antenna radiates toroidally. A method for making an antenna that conforms to the size and shape of a particular system is also disclosed.
