Patent ID: 8487824

Claim:
A polarized antenna comprising: a bicone having a top conductive cone and a bottom conductive cone each of which have an identical conical radius R B and identical physical dimensions, wherein said top conductive cone and said bottom conductive cone are disposed in an oppositely directed stacked configuration along a vertical antenna axis, wherein the combined lengths of said top conductive cone and said bottom conductive cone equal a bicone height; at least one grid layer of grid angle θ, where θ is greater than zero degrees but not greater than forty five degrees, each said grid layer having a grid height at least equal to the bicone height, each said grid layer wrapped one circumferential length around the top conductive cone and the bottom conductive cone in a cylindrical arrangement with a radius greater than the bicone radius R B , and each said at least one grid layer having a constant space between any adjacent at least one grid layer, wherein the radius of each grid layer is directly related to a predetermined frequency; and a zero degree grid layer, with a grid angle of zero degrees with reference to an axis perpendicular to the vertical antenna axis, having a grid height equal to or larger than the bicone height and a radius R 0 , where R 0 is greater than R B , said zero degree grid layer wrapped one circumferential length around the top conductive cone and the bottom conductive cone in a cylindrical configuration disposed between the bicone radius R B and an innermost at least one grid layer.
