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.

16. A method for using a variable inclination continuous transverse stub (VICTS) antenna array to provide a first antenna pattern and a second antenna pattern different from the first antenna pattern, the VICTS array including a feed network for transmitting and/or receiving a signal via radio frequency (RF) coupling, and a conductive plate structure having a first set of continuous transverse stub radiators arranged on a first region of a first surface and a second set of continuous transverse stub radiators arranged on second region of the first surface, wherein i) an area occupied by the first region is larger than an area occupied by the second region, ii) the first region is located between the feed network and the second region, and iii) a geometry of the first set of continuous transverse stub radiators is different from a geometry of the second set of continuous transverse stub radiators, the method comprising:
-
generating the first antenna pattern by positioning the conductive plate structure relative to the feed network to RF couple the first set of continuous transverse stub radiators to the feed network; and generating the second antenna pattern by positioning the conductive plate structure relative to the feed network to RF couple the second set of continuous transverse stub radiators to the feed network.
