PHASED ARRAY ANTENNA

摘要

An antenna element having a vertically stacked structure and a phased array antenna that includes a plurality of antenna elements sharing a common conductive ground plane are described. The phased array antenna also includes a common conductive shell electrically coupled to the common conductive ground plane and extending away there from to encompass the antenna elements. The common conductive shell and the common conductive ground plane together define a common cavity having a common aperture. The phased array antenna also includes a common dielectric superstrate layer disposed over the common cavity at a predetermined distance from the antenna elements and a beam steering system coupled to the antenna elements and configured for steering an energy beam produced by the phased array antenna.

1. A phased array antenna comprising:
a plurality of antenna elements sharing a common conductive ground plane for all the antenna elements and spaced apart at a predetermined distance from each other; a common conductive shell electrically coupled to said common conductive ground plane and extending away there from to encompass said plurality of the antenna elements, said common conductive shell and said common conductive ground plane together define a common cavity having a common aperture; a common dielectric superstrate layer disposed over said common cavity at a predetermined distance from said plurality of the antenna elements; and a beam steering system coupled to said plurality of the antenna elements and configured for steering an energy beam produced by said phased array antenna.
