Conformal load bearing antenna structure
First Claim
1. A conformal load-bearing antenna structure for attachment to an aircraft having an outer skin, the antenna comprising:
- a top face sheet;
an end fed radiating element disposed adjacent to the top face sheet;
a dielectric disposed adjacent to the end fed radiating element;
a structural core disposed adjacent to the dielectric;
a bottom face sheet disposed adjacent to the structural core;
an absorber disposed adjacent to the bottom face sheet; and
an absorber pan disposed adjacent to the absorber;
wherein the top face sheet, the dielectric, the structural core, and the bottom face sheet are configured to provide structural strength to the aircraft when the antenna is attached to the outer skin of the aircraft.

Abstract
A conformal load bearing antenna structure for attachment to an aircraft having an outer skin. The conformal load bearing antenna structure comprises a top face sheet and an end fed radiating element disposed thereon. Disposed adjacent to the top face sheet is a dielectric and a structural core disposed adjacent to the dielectric. In the preferred embodiment, a bottom face sheet is disposed adjacent to the structural core and an absorber is disposed adjacent to the bottom face sheet. Accordingly, the top face sheet, the dielectric, the structural core, and the bottom face sheet are configured to provide structural strength to the aircraft when the antenna is attached to the outer skin thereof.
