Planar, Phased Array Antenna
US Patent:
5563613, Oct 8, 1996
Filed:
Feb 21, 1995
Appl. No.:
8/395378
Inventors:
Gerry B. Schroeder - Fountain Hills AZ
Larry T. Davis - Fountain Hills AZ
Larry T. Davis - Fountain Hills AZ
Assignee:
Schroeder Development - Fountain Hills AZ
International Classification:
H01Q 138
US Classification:
343700MS
Abstract:
A planar, phased array antenna includes a ground plate, a signal plate having a plurality of hollow active elements and conductive branches electrically connecting said active elements in mirror symmetrical pairs, an aperture plate having a plurality of apertures oriented in the same direction and aligned with said active elements to provide electromagnetic coupling between each active element and the corresponding aperture, and spacers between the plates. The ground plate is formed on a first spacer, e. g. by screen printing, and the aperture plate is formed on the other spacer, e. g. by screen printing. The signal plate includes an insulating substrate and a patterned conductive layer on said substrate. Alternatively, the aperture plate is separate from the other spacer and includes an insulating substrate and a patterned conductive layer on the substrate.
