Abstract
A micro-helix antenna. The antenna comprises a helically-shaped conductive element disposed on a dielectric core. The diameter of the helix formed by the conductive element is very small relative to the wavelength of the antenna, preferably no more than about 1/100th of the wavelength. Having such a small diameter, this micro-helix antenna can be further compressed into two- and three-dimensional shapes, such as spirals, helices and meandering or stochastic patterns. The micro-helix antenna can be created by pressing a fine wire into a helical shape. Alternately, the helical conductor can be formed by a laser ablation process or laying down the helical shape using a direct-write process.
