Comformal phased array antenna and method for repair

A phased array antenna comprising:

• an array of radio frequency (RF) modules;
• a planar aperture honeycomb structure defining a plurality of passages in communication with respective RF modules;
• and
• a contoured aperture honeycomb structure defining a plurality of passages extending between opposed first and second surfaces, said contoured aperture honeycomb structure disposed with respect to said planar aperture honeycomb structure such that respective passages of said contoured and planar aperture honeycomb structures are aligned, said contoured aperture honeycomb structure also disposed with respect to said planar aperture honeycomb structure such that the first surface of said contoured aperture honeycomb structure faces said planar aperture honeycomb structure and the second surface faces away from said planar aperture honeycomb structure, wherein the second surface of said contoured aperture honeycomb structure is contoured such that at least portions of the second surface are at an oblique angle with respect to a surface of said planar aperture honeycomb structure.

An assembly comprising:

• a structure having a contoured surface;
• and
• a conformal phased array antenna comprising:
• a planar antenna subassembly comprising an array of radio frequency (RF) modules disposed in a reference plane;
• and
• a contoured waveguide subassembly comprising a contoured aperture honeycomb structure defining a plurality of passages extending between opposed first and second surfaces, said contoured aperture honeycomb structure disposed with respect to said planar antenna subassembly such that each RF module is in communication with a respective passage of said contoured aperture honeycomb structure, said contoured aperture honeycomb structure also disposed with respect to said planar antenna subassembly such that the second surface of said contoured aperture honeycomb structure faces away from said planar antenna subassembly and is contoured such that at least portions of the second surface are at an oblique angle with respect to the reference plane and further such that the contoured second surface conforms with at least portions of the contoured surface of said structure proximate said conformal phased array antenna.
