ABSTRACT:
A structural phased array antenna and method for manufacturing are disclosed. An integrated structural antenna aperture can be used to reduce net weight, cost, and volume where an array of antenna elements are incorporated into a structural member, e.g. in a spacecraft. A structural material layer, such as a structural foam, may be used with the array of individual antenna element cavities machined into the layer. The antenna element cavities are lined with a conductive material, such as plated aluminum. Facesheets may be bonded to the front and/or backside of the structural material layer in order to increase strength and/or stiffness using an RF transparent material. The array of antenna elements may be coupled to filters at the back side of structural material layer.
