Transmitarray based Metasurface Lens Antenna
A transmitarray metasurface design is proposed to function as an integrated lens antenna within the frequency range of 11.6 GHz to 13.25 GHz. A finite periodic array of three layer metallo dielectric discrete unit cells is used to form the transmitarray lens. The transmitarray is used in front of an open ended waveguide to obtain more directive radiation. The transmitarray lens is shown to provide at least 3.75 dB higher gain than a comparable standard horn antenna whilst occupying about half of the physical space.
