Clustered Phased Array Antenna

View page
US Patent:
5512906, Apr 30, 1996
Filed:
Sep 12, 1994
Appl. No.:
8/304252
Inventors:
Ross A. Speciale - Redondo Beach CA
International Classification:
H01Q 322
US Classification:
342375
Abstract:
An array of antenna elements is configured in a lattice-like layer, each element being similarly oriented such that the whole of the antenna elements form a homogeneous two-dimensional antenna aperture surface which can be planar or curved to conform to a desired shape. The antenna elements are connected in a one-to-one correspondence to a matching lattice of mutually similar, multiple-port, wave coupling networks physically extending behind the antenna element array as a backplane of the antenna. Each wave coupling network or "unit cell" couples signals to and/or from its corresponding antenna element and further performs as a phase delay module in a two-dimensional signal distribution network. This invention can be embodied in a conformal, or planar phased array antenna comprising a system of densely-packed resonant cavities feeding a set of resonant slot elements, both configured in an matrix array. Instead of using a corporate feed network to feed each cavity, the array is fed from points on the edges of the array, with each cavity being electromagnetically coupled to each of its adjacent cavities by common wall-coupling means.

US Patent:
5347287, Sep 13, 1994
Filed:
Apr 19, 1991
Appl. No.:
7/687662
Inventors:
Ross A. Speciale - Redondo Beach CA
Assignee:
Hughes Missile Systems Company - Los Angeles CA
International Classification:
H01Q 322
US Classification:
342375
Abstract:
An array of antenna elements are configured in a lattice-like layer, each element being similarly oriented such that the elements form a two-dimensional antenna aperture that may form a planar or curved surface of a desired shape. The antenna elements are connected in a one-to-one correspondence in both number and form to a lattice of identical, multiport, isotropic, wave-coupling networks physically located under the antenna element array as a backplane of the antenna element layer. Each wave-coupling network or "unit cell" couples signals to and/or from its corresponding antenna element and further functions as a phase delay module in a two-dimensional signal distribution network. This invention can be embodied in a two-dimensional signal distribution network and in a wrap-around, conformal, millimeter-wave, phased array antenna, such as on the nose of a missile. A backplane of densely-packed resonant cavities feeds an outboard-facing layer of resonant slots configured in a rectangular or hexagonal lattice for maximum density.
