1. An antenna connected to a radio communications device by first and second conductors, said antenna comprising:

  • a first conductive panel-shaped open-weave mesh element, said first conductor being connected to one edge of said element;

    a second generally solid planar conductive element having an edge adjacent to said one edge of said mesh element and connected to said second conductor, wherein said first and second conductors are proximate alongside one of said conductive elements;

    a container completely enclosing and generally spaced apart from said conductive elements, said container being made of a dielectric material;

    wherein said container is composed of material having a dielectric constant greater than 2;

    wherein said generally planar element is a thin parallelepiped made of brass shim stock material having a thickness ranging from 0.13 mm to 0.25 mm;

    wherein said mesh element is a parallelepiped made of brass wire 0.0254 cm in diameter woven in a 40×

    40 mesh, having 40 openings per 2.54 cm vertically, 40 openings per 2.54 cm horizontally;

    wherein said conductors are within a coaxial cable having a specific diameter, said coaxial cable comprising an outer insulating jacket, a shielding sleeve acting as the first conductor, an intermediate insulator, and a central lead forming the second conductor; and

    wherein the distance between said adjacent edges is generally equal to the diameter of said coaxial cable.
