1. A three-dimensional position locating system comprising:

  • (a) an essentially two-dimensional antenna element underlying an essentially planar surface;

    (b) an antenna element located in a stylus, coupled to the underlying antenna element through a signal driver and signal processor;

    (c) a three-dimensional structure overlying the underlying antenna element;

    (d) at least one antenna coupling element having a first end proximal to the underlying antenna element and having a second end near a surface of the three-dimensional structure; and

    (e) an audio generating circuit coupled to the signal processor and responsive to the position located using the stylus.
