1. An ultra-wide band antenna with predictable polarization and directivity for creating and capturing an electromagnetic field comprising:

  • (a) a voltage source supplying a current;

    (b) a first transmission line embedded in a shielding medium attached to said voltage source for carrying said current;

    (c) a second transmission line embedded in a shielding medium attached to said first transmission line for carrying said current;

    (d) an electrically conductive radiating member embedded in a potting medium for carrying said current and attached to said first and second transmission lines for carrying said current, said current carried by said electrically conductive radiating member cancelled by said current carried by said second transmission line.
