Abstract
An antenna array employing continuous transverse stubs as radiating elements includes a first conductive plate structure including a first set of continuous transverse stubs arranged on a first surface, and a second set of continuous transverse stubs arranged on the first surface, wherein a geometry of the first set of continuous transverse stubs is different from a geometry of the second set of continuous transverse stubs. A second conductive plate structure is disposed in a spaced relationship relative to the first conductive plate structure, the second conductive plate structure having a surface parallel to the first surface. A relative rotation apparatus imparts relative rotational movement between the first conductive plate structure and the second conductive plate structure.
