Wideband High-Gain and Low Scattering Antenna Using Shared-Aperture Metamaterial Superstrate
In this paper, a novel wideband high-gain and low scattering antenna using shared-aperture metamaterial superstrate (SAMS) is designed, fabricated and measured. The superstrate unit cell consisting of two frequency selective surface (FSS) layers with a positive reflection phase gradient is designed to enhance the antenna gain. Then, three different sizes of single units are arranged as a shared-aperture configuration to form the metamaterial superstrate, which is loaded onto the antenna.
