Claim Text:
1. An antenna device comprising: a first reconfigurable radial waveguide structure; a first line feed connected at substantially a center of a surface of the first reconfigurable radial waveguide structure; a second reconfigurable radial waveguide structure coupled to the first reconfigurable radial waveguide structure, wherein the second reconfigurable radial waveguide structure is substantially parallel to and faces the first reconfigurable radial waveguide structure; a second line feed connected at substantially a center of a surface of the second reconfigurable radial waveguide structure, wherein the first line feed of the first reconfigurable radial waveguide structure faces the second line feed of the second reconfigurable radial waveguide structure; a plurality of radiating elements positioned between the first reconfigurable radial waveguide structure and the second reconfigurable radial waveguide structure, and distributed radially around a circumference of the first reconfigurable radial waveguide structure and a circumference of the second reconfigurable radial waveguide structure; and a plurality of direct current (DC) switches coupled to the first reconfigurable radial waveguide structure and the second reconfigurable radial waveguide structure, and configured to switch selected tunable elements in a plurality of tunable elements in the first reconfigurable radial waveguide structure and the second reconfigurable radial waveguide structure.
