Split-Ring Resonator Loaded Miniaturised Slot for the Slotted Waveguide Antenna Stiffened Structure
Abstract
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.
