Wideband Metamaterial lens Antenna for Millimeter-wave Communications

Abstract

A novel lens antenna based on metamaterial technology is proposed for millimeter-wave communications. High directivity is obtained owing to use true-time-delay and space filtering technology. The millimeter-wave lens antenna proposed in this paper can work in wideband. Its unit structure is larger than the traditional millimeter-wave lens which is easier to manufacture. It can be produced by PCB printing and laminating, reducing the production cost and difficulty. The antenna has wide bandwidth and stable directivity. The simulation result shows that 3dB bandwidth and maximum directivity are 28Ghz-32Ghz and 25.8dBi respectively.
