In this paper a new concept for designing subwavelength-profile and broadband high-gain leaky-wave antennas is presented. It is based on novel multi-layer periodic arrays for sub-wavelength Fabry-Perot leaky-wave antennas with enhanced bandwidth performance. Two double-layer periodic arrays of dissimilar dimensions are designed and optimized, each double-layer array consisting of an Artificial Magnetic Conductor (AMC) and a Partially Reflective Surface (PRS) printed on either side of a dielectric substrate. They are separated by subwavelength distances from a ground plane and from each other, creating two air cavities with a total profile less than λ/2. A broadband feeding mechanism is employed. Two antennas are proposed, simulated in CST Microwave Studio™, achieving high gain and broad bandwidth.
