Abstract

Novel meta-surfaces for designing broadband highly directive Fabry-Perot type antennas are presented. The proposed structure is based on novel optimized multi-layer periodic surfaces that create multiple sub-wavelength cavities 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. The two double-layer metasurfaces are placed at about quarter wavelength from a ground plane and from each other. An antenna of 18.3dBi directivity and 8% 3-dB radiation bandwidth is obtained.
