摘要:
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.

摘要:
In one embodiment a method to form a load bearing antenna aperture comprises forming a honeycomb core structure having a plurality of wall sections, the wall sections including electromagnetic radiating elements, and wherein lower surfaces of the wall sections defines a first surface and upper surfaces of the wall sections define a second surface, positioning a back skin to the first surface of the honeycomb core structure with an adhesive layer which comprises a layer of adhesive film and a paste adhesive disposed on the layer of adhesive film. Other embodiments are disclosed.
