ABSTRACT:
An apparatus for radiating a magnetic field of substantially uniform magnitude along an axis in a volume of space having width, height and depth directions includes a first coil arranged in the width and height directions and has a first imaginary point as its center. A second coil is arranged in the width and height directions with a second imaginary point at its center and is spaced from the first coil. The first and second coils each have a side and a predetermined configuration and are positioned adjacent each other, in opposite and facing configuration. The first and second coils are spaced by a distance in the range of 2.0 to 0.1 times the length of one of the coil sides. The first and second coils provide in response to a current applied to the coils, a substantially uniform field within the volume of space being located between first and second imaginary points and extending in the depth direction. Also an antenna structure for providing a three dimensional powering field of substantially constant magnitude is disclosed and includes three orthogonal coil pairs.
