Patent ID: 8477079

Claim:
An antenna comprising: a first flat sheet of conductive material in a first plane; a second flat sheet of conductive material in a second plane that is parallel to the first plane; a third flat sheet of conductive material in a third plane that is parallel to the first plane; an electrical connection between a portion of the edge of the second sheet and the first sheet; a connection port comprising a first electrical connection point on the second sheet and a second electrical connection point on the third sheet; wherein the third sheet is electrically isolated from the first sheet; wherein the distance between the third plane and the first plane is at least one half of the distance between the second plane and the first plane; wherein the distance between the first plane and the second plane is less than: (i) the square root of the area of the first sheet, and (ii) the square root of the area of the second sheet; wherein the distance between the first plane and the third plane is less than: (i) the square root of the area of the first sheet, and (ii) the square root of the area of the third sheet.
