Claim Text:
1. An antenna capable of being joined to an antenna feed comprising: a conductive radiator being substantially tubular and having a slot formed therein from a first end of the conductive radiator to a second end of the conductive radiator, the antenna feed being connectable to the tubular region adjacent to and across the slot; an anisotropic plate positioned a uniform distance from a surface of said conductive radiator, centered above the slot, and extending from the first end of said conductive radiator to the second end of said conductive radiator, said anisotropic plate being electrically insulated from said conductive radiator; and an anisotropic tube positioned a uniform distance from a surface of said conductive radiator and a second uniform distance from said anisotropic plate, said anisotropic tube being electrically insulated from said conductive radiator and said anisotropic plate.
