1. An antenna comprising:

  • a first electrically conductive disc;

    a second electrically conductive disc of substantially the same size as said first electrically conductive disc and aligned substantially in parallel therewith;

    first means for application of an electrical signal to and at a substantially geometric center of one of said first and second electrically conductive discs;

    a plurality of electrically conductive shunts, each of said shunts being electrically connected at a first end thereof to said first electrically conductive disc to a point on a perimeter of said first electrically conductive disc and at a second end thereof to said second electrically conductive disc to a point on a perimeter of said second electrically conductive disc,whereby said second electrically conductive disc and said first electrically conductive disc are spaced from each other by a volume of free space.
