Abstract
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.
Claims19
A load bearing antenna aperture assembly, comprising:
- 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;
- a first adhesive pack disposed on the first surface, wherein the adhesive pack comprises:
- a layer of adhesive film;
- and
- a paste adhesive disposed on the layer of adhesive film;
- a back skin disposed on to the first surface of the honeycomb core structure by the first adhesive pack;
- an antenna electronics board disposed adjacent at least a portion of the back skin, wherein:
- the antenna electronics board comprises a plurality of antenna feed elements arranged in a predetermined pattern;
- and
- the first layer of adhesive film comprises a plurality of rebates formed in a predetermined pattern corresponding to the predetermined pattern of antenna feed elements.
An apparatus comprising:
- a core having a plurality of walls defining a number of cells, the cells comprising radiating elements of an antenna, and the core defining a surface;
- a layer of film positioned on the surface of the core;
- and
- a plurality of adhesive packs positioned on the layer of film, the adhesive packs providing connections to the radiating elements and an electronics board of the antenna;
- and
- a plurality of rebates, the rebates patterned to correspond to antenna feed elements on the electronics board.
An antenna comprising;
- a plurality of walls comprising a core structure having a number of cells, the plurality of walls comprising radiating elements of the antenna, the core structure defining a first surface;
- a backskin positioned on the first surface of the core, wherein the backskin comprises a number of via holes;
- a layer of film positioned on the backskin such that the layer of film faces the first surface of the core;
- a circuit board positioned proximate the backskin;
- a plurality of rebates, the plurality of rebates patterned to correspond to antenna feed elements on the circuit board, connections between the radiating elements of the antenna and the circuit board provided through the via holes;
- and
- a plurality of adhesive packs positioned on the layer of film, the adhesive packs providing connections to the radiating elements and the circuit board.
A load bearing antenna aperture comprising:
- a plurality of wall elements comprising a core structure having a number of cells, the plurality of wall elements including radiating elements of the antenna, the core structure defining a first surface and a second surface;
- a backskin positioned on the first surface of the core;
- a layer of film positioned on the backskin facing the core structure;
- a circuit board positioned on the backskin facing away from the core structure;
- a plurality of adhesive packs positioned on the layer of film, the plurality of adhesive packs spaced so as to correspond to a dimension of the individual cells, the adhesive packs providing connections to the radiating elements and the circuit board;
- a plurality of rebates, a set of individual rebates positioned around an individual adhesive pack;
- and
- a load supported on the second surface of the core.
