Abstract

A new concept for designing subwavelength-profile and broadband high-gain leaky-wave antennas is introduced. A novel multi-layer periodic array design is proposed for subwavelength 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 placed at about quarter wavelength from a ground plane and from each other. Thus, two air cavities are created with a total profile of less than λ/2. The proposed antenna has been simulated (using CST Microwave Studio™) achieving 18.3dBi directivity with 8% bandwidth. This gain-bandwidth product outperforms any previous Fabry-Perot antenna design with this profile.
