1. An antenna array employing continuous transverse stubs as radiating elements, comprising:
- an upper conductive plate structure comprising a set of continuous transverse stubs;
a lower conductive plate structure disposed in a spaced relationship relative to the upper plate structure, said lower plate structure having an upper surface whose spacing from a lower surface of the upper plate varies in a first direction parallel to said lower surface; and
relative rotation apparatus for imparting a relative rotational movement between said upper plate structure and said lower plate structure.

Abstract
An antenna array employing continuous transverse stubs as radiating elements is disclosed. In an exemplary embodiment, the array includes an upper conductive plate structure comprising a set of continuous transverse stubs, and a lower conductive plate structure disposed in a spaced relationship relative to the upper plate structure. A rotation apparatus provides rotation between the upper plate structure and the lower plate structure.

37. A Variable Inclination Continuous Transverse Stub (VICTS) array comprising:
-
a first plate structure comprising a one-dimensional lattice of continuous radiating stubs;
a second plate structure comprising one or more line sources emanating into a parallel-plate region formed and bounded between the first and second plate structures;
an apparatus for imparting relative rotational movement between the upper plate structure and the lower plate structure, whereby said rotation acts to vary the inclination of incident parallel-plate modes relative to the continuous radiating stubs in the upper plate, and in doing so constructively exciting a radiated planar phase-front whose angle relative to a mechanical normal of the array is a function of a relative angle of differential mechanical rotation between the two plates; and
a choke structure between the first plate structure and the second plate structure for preventing escape of spurious TR energy outside boundaries of the array. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
