Abstract:
An antenna system, comprising:a planar first antenna element including a planar first end portion, whereon said planar first antenna element has a width and a length, wherein said width is at least one-half as great as said length, and wherein said planar first antenna element has a lower surface;a planar second antenna element including a planar first end portion, with said second antenna element being spaced from said first antenna element, wherein said planar second antenna element has a width and a length wherein said width is at least one-half as great as said length wherein said planar second antenna element has an upper surface, and wherein a majority of said lower surface of said planar first antenna element overlays a majority of said upper surface of said planar second antenna element;a ground member spaced from at least substantial portions of each of said first and second antenna elements; andat least a first tuning element having a length with a center axis, said first tuning element being connected to and extending through said first antenna element, said first tuning element having first and second positions, when said first tuning element is in said first position, said center axis is perpendicular to said planar first end portion and when said first tuning element is in said second position, said planar first end portion of said planar first antenna element is at an angle different from perpendicular to said center axis.
