1. A three-dimensional multiple spiral antenna comprising:

  • a substrate having a plurality of substantially planar layers and a three-dimensional shaped region formed thereon;

    a plurality of circuit components residing upon at least two differing substantially planar layers of the plurality of substantially planar layers;

    a plurality of spiral antenna sections, wherein each spiral antenna section of the plurality of spiral antenna sections is supported by a corresponding section of the three-dimensional shaped region and conforms to the corresponding section of the three-dimensional shaped region such that, collectively, the plurality of spiral antenna sections has an overall shape approximating the three-dimensional shaped region;

    a feed point module; and

    a common coupling circuit that couples connection points of the plurality of spiral antenna sections to the feed point module.
