The increasing use carbon fibre reinforced polymer CFRP in modern military aircraft together with the desire for a conformal load-bearing antenna structure, has since inspired the slotted waveguide antenna stiffened structure (SWASS) (concept 1). Conventional hat stiffened or blade stiffened aircraft panels fabricated in CFRP coincidentally exhibit internal dimensions that are typical of common military waveguide bands. By machining resonant slots at half- wavelength intervals in the outer skin of the stiffened panel, a SWA may be integrated into the aircraft structure to achieve potential weight and drag improvements over conventional aircraft antennas. These slots may be filled with a low-loss dielectric to retain the aerodynamic performance of the panel or with a high dielectric to reduce their physical dimensions.
