Abstract

An antenna is provided. The antenna may include at least one open-ended structure extending from a surface of a waveguide. The open-ended structure may have a cross section of many different shapes. The walls of the structure may be movable. The antenna structure may be rotated. The antenna may incorporate a number of different wave feeds. The antenna may provide two-dimensional beam steering.

Claims

26AMENDED CLAIMS received by the International Bureau on 08 September 2008 (08.09.2008)
1. An antenna comprising; a parallel plate waveguide having a top plate, a bottom plate, and a backside, at least one radiating element extending from the top plate of the waveguide over an aperture formed in the top plate, the element comprising a sidewall forming a distal opening spaced apart from the top plate of the waveguide, and wherein the center of the aperture is formed at a distance L from the backside, the distance L selected so that a reflecting wave reflected from the backside returns in phase with a propagating wave that is propagating towards the backside.
2. The antenna of Claim 1 , wherein the at least one radiating element comprises an extruded portion having a proximal end and a distal end, and further comprising at least one wall portion extending from the proximal end to the distal end, and wherein the extruded portion forms a tube having openings at the proximal end and the distal end.
3. The antenna of Claim 1 , wherein the at least one radiating element has a polygonal cross section.
4. The antenna of Claim 1, wherein the at least one radiating element has a curved cross section.
